- * @class Ext.data.Store
- * @extends Ext.util.Observable
- * <p>The Store class encapsulates a client side cache of {@link Ext.data.Record Record}
- * objects which provide input data for Components such as the {@link Ext.grid.GridPanel GridPanel},
- * the {@link Ext.form.ComboBox ComboBox}, or the {@link Ext.DataView DataView}.</p>
- * <p><u>Retrieving Data</u></p>
- * <p>A Store object may access a data object using:<div class="mdetail-params"><ul>
- * <li>{@link #proxy configured implementation} of {@link Ext.data.DataProxy DataProxy}</li>
- * <li>{@link #data} to automatically pass in data</li>
- * <li>{@link #loadData} to manually pass in data</li>
- * </ul></div></p>
- * <p><u>Reading Data</u></p>
- * <p>A Store object has no inherent knowledge of the format of the data object (it could be
- * an Array, XML, or JSON). A Store object uses an appropriate {@link #reader configured implementation}
- * of a {@link Ext.data.DataReader DataReader} to create {@link Ext.data.Record Record} instances from the data
- * object.</p>
- * <p><u>Store Types</u></p>
- * <p>There are several implementations of Store available which are customized for use with
- * a specific DataReader implementation. Here is an example using an ArrayStore which implicitly
- * creates a reader commensurate to an Array data object.</p>
- * <pre><code>
-var myStore = new Ext.data.ArrayStore({
- fields: ['fullname', 'first'],
- idIndex: 0 // id for each record will be the first element
-});
- * </code></pre>
- * <p>For custom implementations create a basic {@link Ext.data.Store} configured as needed:</p>
- * <pre><code>
-// create a {@link Ext.data.Record Record} constructor:
-var rt = Ext.data.Record.create([
- {name: 'fullname'},
- {name: 'first'}
-]);
-var myStore = new Ext.data.Store({
- // explicitly create reader
- reader: new Ext.data.ArrayReader(
- {
- idIndex: 0 // id for each record will be the first element
- },
- rt // recordType
- )
-});
- * </code></pre>
- * <p>Load some data into store (note the data object is an array which corresponds to the reader):</p>
- * <pre><code>
-var myData = [
- [1, 'Fred Flintstone', 'Fred'], // note that id for the record is the first element
- [2, 'Barney Rubble', 'Barney']
-];
-myStore.loadData(myData);
- * </code></pre>
- * <p>Records are cached and made available through accessor functions. An example of adding
- * a record to the store:</p>
- * <pre><code>
-var defaultData = {
- fullname: 'Full Name',
- first: 'First Name'
-};
-var recId = 100; // provide unique id for the record
-var r = new myStore.recordType(defaultData, ++recId); // create new record
-myStore.{@link #insert}(0, r); // insert a new record into the store (also see {@link #add})
- * </code></pre>
- * <p><u>Writing Data</u></p>
- * <p>And <b>new in Ext version 3</b>, use the new {@link Ext.data.DataWriter DataWriter} to create an automated, <a href="http://extjs.com/deploy/dev/examples/writer/writer.html">Writable Store</a>

- * @class Ext.data.DataProxy
- * @extends Ext.util.Observable
- * <p>Abstract base class for implementations which provide retrieval of unformatted data objects.
- * This class is intended to be extended and should not be created directly. For existing implementations,
- * see {@link Ext.data.DirectProxy}, {@link Ext.data.HttpProxy}, {@link Ext.data.ScriptTagProxy} and
- * {@link Ext.data.MemoryProxy}.</p>
- * <p>DataProxy implementations are usually used in conjunction with an implementation of {@link Ext.data.DataReader}
- * (of the appropriate type which knows how to parse the data object) to provide a block of
- * {@link Ext.data.Records} to an {@link Ext.data.Store}.</p>
- * <p>The parameter to a DataProxy constructor may be an {@link Ext.data.Connection} or can also be the
- * config object to an {@link Ext.data.Connection}.</p>
- * <p>Custom implementations must implement either the <code><b>doRequest</b></code> method (preferred) or the
- * <code>load</code> method (deprecated). See
- * {@link Ext.data.HttpProxy}.{@link Ext.data.HttpProxy#doRequest doRequest} or
- * {@link Ext.data.HttpProxy}.{@link Ext.data.HttpProxy#load load} for additional details.</p>
- * <p><b><u>Example 1</u></b></p>
- * <pre><code>
-proxy: new Ext.data.ScriptTagProxy({
- {@link Ext.data.Connection#url url}: 'http://extjs.com/forum/topics-remote.php'
-}),
- * </code></pre>
- * <p><b><u>Example 2</u></b></p>
- * <pre><code>
-proxy : new Ext.data.HttpProxy({
- {@link Ext.data.Connection#method method}: 'GET',
- {@link Ext.data.HttpProxy#prettyUrls prettyUrls}: false,
- {@link Ext.data.Connection#url url}: 'local/default.php', // see options parameter for {@link Ext.Ajax#request}
- {@link #api}: {
- // all actions except the following will use above url
- create : 'local/new.php',
- update : 'local/update.php'
- }
-}),
- * </code></pre>
- * <p>And <b>new in Ext version 3</b>, attach centralized event-listeners upon the DataProxy class itself! This is a great place
- * to implement a <i>messaging system</i> to centralize your application's user-feedback and error-handling.</p>
- * <pre><code>
-// Listen to all "beforewrite" event fired by all proxies.
-Ext.data.DataProxy.on('beforewrite', function(proxy, action) {
- console.log('beforewrite: ', action);
-});
-
-// Listen to "write" event fired by all proxies
-Ext.data.DataProxy.on('write', function(proxy, action, data, res, rs) {
- console.info('write: ', action);
-});
-
-// Listen to "exception" event fired by all proxies
-Ext.data.DataProxy.on('exception', function(proxy, type, action) {
- console.error(type + action + ' exception);
-});
- * </code></pre>
- * <b>Note:</b> These three events are all fired with the signature of the corresponding <i>DataProxy instance</i> event {@link #beforewrite beforewrite}, {@link #write write} and {@link #exception exception}.

- * <p>The url is built based upon the action being executed <tt>[load|create|save|destroy]</tt>
- * using the commensurate <tt>{@link #api}</tt> property, or if undefined default to the

- * <p>For example:</p>
- * <pre><code>

- save : '/controller/update',
- destroy : '/controller/destroy_action'

- destroy: 'destroy.php',
- save: 'update.php'
-}
- * </code></pre>
- * <p>If the specific URL for a given CRUD action is undefined, the CRUD action request

- * <br><p><b>Note</b>: To modify the URL for an action dynamically the appropriate API
- * property should be modified before the action is requested using the corresponding before

- * <pre><code>

-myStore.on({
- beforeload: {
- fn: function (store, options) {
- // use <tt>{@link Ext.data.HttpProxy#setUrl setUrl}</tt> to change the URL for *just* this request.

- // set optional second parameter to true to make this URL change
- // permanent, applying this URL for all subsequent requests.
- store.proxy.setUrl('changed1.php', true);
-
- // Altering the proxy API should be done using the public
- // method <tt>{@link Ext.data.DataProxy#setApi setApi}</tt>.
- store.proxy.setApi('read', 'changed2.php');
-
- // Or set the entire API with a config-object.

-out.print(dataBlock.toJsonString());
-if (scriptTag) {

- * <p>Developers may add their own application-specific data types to this class. Definition names must be UPPERCASE.

- * <li><code>convert</code> : <i>Function</i><div class="sub-desc">A function to convert raw data values from a data block into the data

- * <div class="mdetail-params"><ul>
- * <li><b>v</b> : Mixed<div class="sub-desc">The data value as read by the Reader, if undefined will use
- * the configured <tt>{@link Ext.data.Field#defaultValue defaultValue}</tt>.</div></li>
- * <li><b>rec</b> : Mixed<div class="sub-desc">The data object containing the row as read by the Reader.

- * <li><code>type</code> : <i>String</i> <div class="sub-desc">A textual data type name.</div></li>
- * </ul></div>
- * <p>For example, to create a VELatLong field (See the Microsoft Bing Mapping API) containing the latitude/longitude value of a datapoint on a map from a JsonReader data block
- * which contained the properties <code>lat</code> and <code>long</code>, you would define a new data type like this:</p>

- },
- sortType: function(v) {
- return v.Latitude; // When sorting, order by latitude
- },
- type: 'VELatLong'
-};
-</code></pre>
- * <p>Then, when declaring a Record, use <pre><code>
-var types = Ext.data.Types; // allow shorthand type access
-UnitRecord = Ext.data.Record.create([
- { name: 'unitName', mapping: 'UnitName' },
