/**
 * A DataSource is data-provider-independent description of a set of objects that will be loaded, edited and saved within
 * the user interface of your application. <P> Each DataSource consists of a list of {@link
 * com.smartgwt.client.data.DataSource#getFields fields} that make up a DataSource <code>record</code>, along with {@link
 * com.smartgwt.client.data.DataSourceField#getType field types},  {@link
 * com.smartgwt.client.data.DataSourceField#getValidators validation rules},  {@link
 * com.smartgwt.client.data.DataSourceField#getForeignKey relationships} to other DataSources, and other metadata. <P> The
 * abstract object description provided by a DataSource is easily mapped to a variety of backend object models and storage
 * schemes.  The following table shows analogous terminology across systems. <table border=1 class="normal"> <tr>  
 * <td>Isomorphic Smart GWT</td>   <td>Relational Database</td>   <td>Enterprise Java Beans (EJB)</td>  
 * <td>Entity/Relationship Modeling</td>   <td>OO/UML</td>   <td>XML Schema/WSDL</td>   <td>LDAP</td> </tr><tr>  
 * <td>DataSource</td>   <td>Table</td>   <td>EJB class</td>   <td>Entity</td>   <td>Class</td>   <td>Element Schema
 * (ComplexType)</td>   <td>Objectclass</td> </tr><tr>   <td>Record</td>   <td>Row</td>   <td>EJB instance</td>  
 * <td>Entity instance</td>   <td>Class instance/Object</td>   <td>Element instance (ComplexType)</td>   <td>Entry</td>
 * </tr><tr>   <td>Field</td>   <td>Column</td>   <td>Property</td>   <td>Attribute</td>   <td>Property/Attribute</td>  
 * <td>Attribute or Element (SimpleType)</td>   <td>Attribute</td> </tr></table> <P> DataSources can be {@link
 * com.smartgwt.client.docs.DataSourceDeclaration declared} in either JavaScript or XML format, and can also be {@link
 * metadataImport imported} from existing metadata formats, including XML Schema. <P> <i>Data Binding</i> is the process by
 * which {@link com.smartgwt.client.widgets.DataBoundComponent Data Binding-capable UI components} can automatically
 * configure themselves for viewing, editing and saving data described by DataSources.  DataBinding is covered in the
 * 'QuickStart Guide', Chapter 6, <i>Data Binding</i>. <P> {@link com.smartgwt.client.docs.ClientServerIntegration Data
 * Integration} is the process by which a DataSource can be connected to server systems such as SQL DataBases, Java Object
 * models, WSDL web services and other data providers.  Data Integration comes in two variants: client-side and
 * server-side.  {@link com.smartgwt.client.docs.ServerDataIntegration Server-side integration} uses the Smart GWT
 * Java-based server to connect to data represented by Java Objects or JDBC-accessible databases.  {@link
 * com.smartgwt.client.docs.ClientDataIntegration Client-side integration} connects Smart GWT DataSources to XML, JSON or
 * other formats accessible via HTTP. <P> DataSources have a concept of {@link
 * com.smartgwt.client.docs.DataSourceOperations 4 core operations} ("fetch", "add", "update" and "remove") that can be
 * performed on the set of objects represented by a DataSource.  Once a DataSource has been integrated with your data
 * store, databinding-capable  UI components can leverage the 4 core DataSource operations to provide many complete user
 * interactions without the need to configure how each individual component loads and saves data. <P> These interactions
 * include {@link com.smartgwt.client.widgets.grid.ListGrid grid views}, {@link com.smartgwt.client.widgets.tree.TreeGrid
 * tree views},  {@link com.smartgwt.client.widgets.viewer.DetailViewer detail views}, {@link
 * com.smartgwt.client.widgets.form.DynamicForm form}-based  {@link com.smartgwt.client.widgets.form.DynamicForm#editRecord
 * editing} and {@link com.smartgwt.client.widgets.form.DynamicForm#saveData saving}, grid-based {@link
 * com.smartgwt.client.widgets.grid.ListGrid#getCanEdit editing} and {@link
 * com.smartgwt.client.widgets.grid.ListGrid#getSaveByCell saving}, and custom interactions provided by <a
 * href="http://www.smartclient.com/smartgwt/showcase/#pattern_reuse_grid_form_category" target="examples">Pattern Reuse
 * Example</a> custom databinding-capable components.

     * With ordinary {@link com.smartgwt.client.data.Criteria simple criteria}, it is possible to provide an array

     *   var criteria = {
     *     field1 : "value1",
     *     field2 : ["value2", "value3"]
     *  }</pre>
     *  At first glance, this criteria appears to mean "select records where 'field1' is 'value1'
     *  and 'field2' is one of 'value2' or 'value3'".  However, if the prevailing 
     *  {@link com.smartgwt.client.data.DSRequest#getTextMatchStyle textMatchStyle} is "substring" - as it would be if, for
     *  example, you had issued a {@link com.smartgwt.client.data.DataSource#filterData filterData()} call - then this 
     *  criteria means "select records where 'field1' contains 'value1' somewhere, and 'field2'
     *  contains either 'value2' or 'value3'"
     *  <p>
     *  Depending on your requirement, this may or may not be what you want, and you can control
     *  it by setting the <code>textMatchStyle</code> on your {@link com.smartgwt.client.data.DSRequest}, or by
     *  setting a default <code>textMatchStyle</code> on the DataSource 
     * ({@link com.smartgwt.client.data.DataSource#getDefaultTextMatchStyle defaultTextMatchStyle}), or by specifying that the
     * <code>textMatchStyle</code> 
     * should be ignored for certain fields ({@link com.smartgwt.client.data.DataSourceField#getIgnoreTextMatchStyle
     * DataSourceField.ignoreTextMatchStyle})
     *  <p>
     *  However, a common use case is that you want "substring" style filtering on one or more 
     *  single-valued fields, but exact matching on a list-valued field.  For example, say you
     *  want a list of customers based in certain cities, with a name matching the substring 
     * "software":<pre>
     *   var criteria = {
     *     name : "software",
     *     city : ["York", "Newport", "Orleans"]
     *  }</pre>
     *  Here, using substring matching on the "city" field is likely to give incorrect results,
     *  as it will match a number of US cities in addition to the three European cities 
     *  intended (New York, Yorktown, New Orleans, Newport News, and probably others).  And 
     *  even if this is not an issue for your particular use case, and correct results can be
     *  obtained with a substring search, it is very likely to be more costly performance-wise 
     *  than the exact value match that you really need (potentially much more costly).
     *  <p>  
     *  You could achieve exact matching in the above case by marking the "city" field as 
     *  <code>ignoreTextMatchStyle:true</code>, but that would mean you couldn't perform 
     *  substring searches on that field in other use cases where that might be desirable.  
     *  <p>
     *  In cases like this, Smart GWT by default treats list-valued simple criteria as 
     *  if <code>ignoreTextMatchStyle</code> is in force for that field.  If you want to switch
     *  this behavior off, and have list-valued simple criteria handled with the prevailing 
     *  <code>textMatchStyle</code>, set <code>arrayCriteriaForceExact</code>
     *  to false.  It is also possible to set this flag per-operationBinding and 
     * per-DSRequest - see {@link com.smartgwt.client.data.OperationBinding#getArrayCriteriaForceExact
     * OperationBinding.arrayCriteriaForceExact} and 
     *  {@link com.smartgwt.client.data.DSRequest#getArrayCriteriaForceExact DSRequest.arrayCriteriaForceExact}

     *  This will only have an effect for server-side DataSources; if you want to change this

     *     INSERT INTO myDataSource (field1, field2, field3)

     *         VALUES(1, 'Another test', 73)
     *         . . .
     *         VALUES(8056, 'Final record', 70707)
     *  </pre>
     *  Note, the Oracle database product does not support this syntax, so we implement batch 
     *  insert in a different way - using subselects - with that one database.  This difference
     *  is transparent from the perspective of a Smart GWT developer, and is only mentioned 
     *  for completeness.
     *  <p>
     *  Batch inserting can be configured at the {@link com.smartgwt.client.data.DSRequest DSRequest}, 
     * {@link com.smartgwt.client.data.DataSource DataSource} and {@link com.smartgwt.client.data.OperationBinding
     * OperationBinding} 
     *  levels, and it can also be globally configured in <code>server.properties</code>.  See
     * the {@link com.smartgwt.client.docs.serverds.DataSource#multiInsertStrategy multiInsertStrategy} documentation for
     * details.
     *  <h4>Cache Synchronization and Audit</h4>
     *  This optimized batch insert style of multi-record add only supports 
     *  {@link com.smartgwt.client.data.OperationBinding#getCanSyncCache cache synchronization} in a limited way, because 
     *  database products do not provide a reliable way to determine the generated keys of 
     *  rows inserted in this way.  We support cache synchronization of batch-inserted records
     *  only when<ul>
     *  <li>The DataSource does not specify any "sequence" fields, and</li>
     *  <li>The <code>requestValuesPlusSequences</code> 
     *  {@link com.smartgwt.client.types.CacheSyncStrategy cacheSyncStrategy} is in force</li>
     *  </ul>
     * We support {@link com.smartgwt.client.docs.serverds.DataSource#audit automatic audit} of batch-inserted records only
     * when 
     *  both of the above conditions are true, and the <code>sql.multi.insert.allowAudit</code>
     *  flag is set to <code>true </code> in your <code>server.properties</code> file.
     *  <p>
     *  Additionally, be aware that any values missing from the original request data for 
     *  whatever reason, will also be missing from both the cache-sync data and the audit 
     *  records.
     *  <p>
     *  "Simple" multi-record add, where each record is added with a discrete INSERT, does 
     *  fully support cache-sync by default, but you may wish to consider turning it off when
     *  adding large numbers of records because the extra cache sync fetches can add  
     *  significantly to the overall operation time (note, this only applies to the default
     *  "refetch" cache-sync strategy, so it does not affect the limited cache sync applicable
     *  to optimized batch inserts, described above).  In fact, the elapsed time of a large 
     *  multi-record <code>addData()</code> operation using "simple" multi-insert is more than 
     *  doubled with "refecth" cache sync switched on, with all major databases, and it is 
     *  significantly more than double on some of them.  You can switch off cache sync for an 
     *  operation by setting the {@link com.smartgwt.client.data.OperationBinding#getCanSyncCache canSyncCache} flag to 
     *  <code>false</code> on your <code>OperationBinding</code>; alternatively, you can switch
     *  to <code>cacheSyncStrategy</code> "requestValuesPlusSequences" if that is an option for
     *  your use case (ie, you do not have database-generated field values, or can live without 
     *  them).  Note, auditing is not possible if cache sync is completely switched off.
     *  <p>
     *  <h4>Additional notes</h4>
     *  Please note a couple of provisos about batch inserting; since batch insert has a
     *  specialized and quite narrow set of use cases, we do not currently plan to remove any
     *  of these restrictions<ul>
     *  <li>It is not supported by all database products.  The following databases have been 
     *  tested and verified to work: MySQL/MariaDB, HSQLDB, Microsoft SQL Server, PostgreSQL
     *  Oracle and DB/2.  Other databases may work, but we do not guaranteee it</li>
     *  <li>It is not properly supported with {@link com.smartgwt.client.docs.CustomQuerying SQL templating}.  
     *  If you try to make use of <b>$valuesClause</b> in a custom querying scenario where 
     *  batch inserting is in force, you will only get the <code>valuesClause</code> applicable
     *  to the first valueSet.  The same restriction applies to <b>$values</b> references in 
     *  things like {@link com.smartgwt.client.data.DataSourceField#getCustomInsertExpression custom SQL expressions}</li>
     *  <li>It does not fully support binary fields.  We do support values being sent from the
     *  client for fields of type "binary" as Base64-encoded strings, and we also support 
     *  server-side Java code adding <code>InputStream</code> objects to valueSets before the 
     *  SQL subsystem sees them (for example, by using a {@link com.smartgwt.client.data.DataSource#getServerObject DMI}).
     *  However, we do not support upload of real binary files in a multi-record "add" request,
     *  primarily because there is no clear way to discern which of the records the uploaded
     *  file(s) belong with</li>

     * subsequent,
     *  incremental updates from sources like user editing is fine.
     *  <h4>Batch inserting</h4>
     *  <code>addData()</code> can be passed a {@link com.smartgwt.client.data.List List} of records to insert, 
     *  rather than a single record.  Actual support for this kind of multi-add is entirely

     *  <code>SQLDataSource</code> has support for multi-add out-of-the-box.  If you are using 
     * <code>SQLDataSource</code> (ie, your dataSource's {@link com.smartgwt.client.docs.serverds.DataSource#serverType
     * serverType}
     *  is "sql"), the default behavior of the server when it receives an "add" request with a
     *  list of records is to invoke a single-record add on the <code>DataSource</code> for each
     *  of the records in the provided list.
     *  <p>
     *  However, you can also configure the server to generate a true "batch insert", and this 
     *  will typically be significantly faster.  Instead of generating multiple <code>INSERT</code>

     *  <P>
     *  <b>NOTE:</b> do not attempt to override this method to create a custom DataSource.  For
     * a server-side custom DataSource, use the {@link com.smartgwt.client.docs.serverds.DataSource#serverConstructor
     * serverConstructor} attribute,
     * and the @see <a href="http://www.smartclient.com/smartgwtee/showcase/#customDataSource" target="examples">Custom
     * DataSource samples</a>.  For a
     *  client-side custom DataSource, see {@link com.smartgwt.client.data.DataSource#getDataProtocol dataProtocol:"custom"}.
     *  <P>
     * In contrast to {@link com.smartgwt.client.widgets.grid.ListGrid#fetchData ListGrid.fetchData()}, which creates a {@link
     * com.smartgwt.client.data.ResultSet} to manage
     *  the returned data, calling <code>dataSource.fetchData()</code> provides the returned
     *  data in the callback as a 
     *  
     *  RecordList or simple Array of Record objects.  Calling
     *  <code>dataSource.fetchData()</code> does not automatically update any visual components or
     *  caches: code in the callback passed to <code>fetchData()</code> decides what to do with
     *  the returned data. 
     *  <P>
     *  For example, given a ListGrid "myGrid" and a DataSource "employees", the following code
     *  would populate "myGrid" with data fetched from the DataSource:
     *  <pre>
     *     
     *     DataSource.get("employees").fetchData(null, new DSCallback() {
     *         public void execute(DSResponse response, Object rawData, DSRequest request) {
     *             myGrid.setData(response.getData());
     *         }
     *     });
     *  </pre>
     *  Unlike calling <code>myGrid.fetchData()</code>, which creates a {@link com.smartgwt.client.data.ResultSet}, the
     *  data provided to the grid is "disconnected" data, unmanaged by Smart GWT's databinding
     *  facilities and safe to directly modify.  This is useful when, for example, a ListGrid is
     *  being used as a more sophisticated version of HTML's multi-select component.
     *  <P>
     *  Disconnected datasets may be used to populate various visual components.  For example,
     *  while an individual FormItem can be configured to fetch
     *  {@link com.smartgwt.client.widgets.form.fields.FormItem#getValueMap valueMap} options from a DataSource via the
     * {@link com.smartgwt.client.widgets.form.fields.FormItem#getOptionDataSource optionDataSource} property, the following
     * code shows
     *  storing a dataset to derive valueMaps from later:
     *  <pre>
     *     
     *     
     *       // Assume GlobalStore.allCountries is a public static variable of type RecordList 
     *       DataSource.get("countries").fetchData(null, new DSCallback(){
     *          public void execute(DSResponse response, Object rawData, DSRequest request) {
     *             GlobalStore.allCountries = response.getDataAsRecordList();
     *          }
     *       });
     *       ... later, while a DynamicForm is being created ...    
     *       SelectItem select = new SelectItem("country", "Pick Country");
     *       Map valueMap = GlobalStore.countries.getValueMap("countryId", "countryName");
     *       myItem.setValueMap(new LinkedHashMap(valueMap));
     *     
     *  </pre>
     *  <P>
     *  You can also create a ResultSet from the data retrieved from <code>fetchData()</code>,
     *  like so:
     *  <pre>
     *     
     *     
     *     DataSource.get("countries").fetchData(null, new DSCallback() {
     *         public void execute(DSResponse response, Object rawData, DSRequest request) {
     *             ResultSet rs = new ResultSet(DataSource.get("countries"));
     *             rs.setAllRows(response.getData());
     *         }
     *     });
     *     
     *  </pre>
     *  <P>
     *  This gives you a dataset that supports client-side filtering (via
     *  {@link com.smartgwt.client.data.ResultSet#setCriteria setCriteria()}), can provide 
     *  {@link com.smartgwt.client.data.ResultSet#getValueMap filtered valueMaps}, will 
     *  {@link com.smartgwt.client.data.ResultSet#getDisableCacheSync automatically reflect updates} to the DataSource made via
     *  other components, and can be re-used with multiple visual components.
     *  <P>
     * See also {@link com.smartgwt.client.data.DataSource#getClientOnlyDataSource getClientOnlyDataSource()} and {@link
     * com.smartgwt.client.data.DataSource#getCacheAllData cacheAllData} for
     *  similar capabilities for dealing with smaller datasets entirely within the browser, or working
     *  with modifiable caches representing subsets of the data available from a DataSource.
     *  <P>
     *  See also the server-side com.isomorphic.js.JSTranslater class in the
     *  
     *  
     *  <a href='https://www.smartclient.com/smartgwtee-release/server/javadoc/' target='_blank'>Java Server Reference</a>
     *   for other, similar approaches
     *  involving dumping data into the page during initial page load.  <b>Note:</b> care should
     *  be taken when using this approach.  Large datasets degrade the basic performance of some
     *  browsers, so use  optionDataSource and similar
     *  facilities to manage datasets that may become very large.
     *  <P>
     *  <b>Data-Driven Visual Component Creation</b>
     *  <P>
     *  
     *  
     *  <code>DataSource.fetchData()</code> can also be used to create Smart GWT components in a
     *  data-driven way.  For example, if you had a DataSource "myGridFields" whose fields included the
     *  basic properties of {@link com.smartgwt.client.widgets.grid.ListGridField} (name, title, type,
     *  etc), this example code would create a form based on stored field definitions, loaded from the
     *  "myFormFields" DataSource on the fly: 
     *  <pre>    
     *    DataSource.get("myFormFields").fetchData(null, new DSCallback(){
     *        public void execute(DSResponse response, Object rawData, DSRequest request) {
     *           Record[] records = response.getData();
     *           ListGridField[] fields = new ListGridField[records.length];
     *           for (Record record in records) {
     *               ListGridField field = new ListGridField();
     *               field.setName(record.getAttribute("name"));
     *               field.setTitle(record.getAttribute("title"));
     *               field.setType(ListGridFieldType.valueOf(record.getAttribute("type")));
     *           }
     *           ListGrid grid = new ListGrid();
     *           grid.setFields(fields);
     *        }
     *    });
     *  </pre>  
     *  
     *  This capability to dynamically create visual components from dynamically fetched data
     *  provides a foundation for creating interfaces that can be customized by end users.
     *  See also the server-side API com.isomorphic.datasource.DataSource.addDynamicDSGenerator() for
     *  dynamically creating DataSources supporting all server-side DataSource features, and

     *  <P>

     *  will be serialized as an XML message by {@link com.smartgwt.client.data.DataSource#xmlSerialize xmlSerialize()}.
     *  <P>
     *  As an example, if you have a dataURL that can return paged data given URL parameters
     *  "start" and "end", you could implement transformRequest like so:
     *  
     *  
     *  <pre>
     *       &#64;Override
     *       protected Object transformRequest (DSRequest dsRequest) {

     *               JSOHelper.setAttribute (data, "start", dsRequest.getStartRow());
     *               JSOHelper.setAttribute (data, "end", dsRequest.getEndRow());
     *           }
     *           return data;
     *       }
     *  </pre>
     *  
     *  Other reasons to implement transformRequest():
     *  <ul>
     *  <li> transform a {@link com.smartgwt.client.data.Criteria} object into the custom query language of a web
     *       service
     *  <li> add a session id to requests that require authentication
     *  <li> detect colliding updates by sending both updated values and the values the user
     * originally retrieved before editing began (available as {@link com.smartgwt.client.data.DSRequest#getOldValues
     * DSRequest.oldValues})
     *  </ul>
     *  <i>Special case:</i> If the <code>dataProtocol</code> is <code>"clientCustom"</code>
     *  the Smart GWT system will not attempt to send data to the server in any way. Instead 
     *  transformRequest should be implemented such that it accesses or updates the underlying
     * data-set and calls {@link com.smartgwt.client.data.DataSource#processResponse processResponse()} when the operation is
     * complete. This
     *  setting allows straightforward integration with non Smart GWT comm mechanisms that 
     *  directly send requests to the server (such as GWT-RPC), or handle data manipulation without
     *  sending HTTP at all (such as Google Gears).<br>
     *  Developers should not generate a response for a request and call 
     *  <code>processResponse()</code> synchronously from within <code>transformRequest</code>
     *  as this can lead to unpredictable results. 
     *  If you're integrating with a synchronous data provider or able to process requests
     *  synchronously from data in browser memory, we'd recommend using a
     *  {@link com.smartgwt.client.data.DataSource#getClientOnly clientOnly dataSource} with a custom
     *  {@link com.smartgwt.client.data.DataSource#getClientOnlyResponse getClientOnlyResponse()} implementation instead.
     *  <P>
     * A <code>transformRequest</code> override may also be used to set the {@link
     * com.smartgwt.client.data.DSRequest#getDataProtocol DSRequest.dataProtocol}
     *  to clientCustom at runtime, giving developers a way to intercept normal handling for
     *  some particular request, and provide entirely custom handling written on the client.
     *  <P>
     *  Note: The {@link com.smartgwt.client.data.RestDataSource} class overrides transformRequest() to handle xml-serializing

     *  For example, given criteria like this (in the JSON representation of AdvancedCriteria):
     *  <pre>
     *       { operator: "and", criteria: [

     *         ]
     *       }

     *  This returned criteria is not logically equivalent to the passed criteria - the

     *  <code>flattenCriteria</code> should not be used as a means of simplifying criteria to
     *  make server implementation easier or anything of the kind.  The primary purpose of
     *  returning logically different criteria is to enable an end user to switch from an
