/*! - * Ext JS Library 3.3.1 - * Copyright(c) 2006-2010 Sencha Inc. - * licensing@sencha.com - * http://www.sencha.com/license - */ -/** - * @class Ext.data.Store - * @extends Ext.util.Observable - *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}.
- *Retrieving Data
- *A Store object may access a data object using:
- *- *
- {@link #proxy configured implementation} of {@link Ext.data.DataProxy DataProxy}
- *- {@link #data} to automatically pass in data
- *- {@link #loadData} to manually pass in data
- *Reading Data
- *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.
- *Store Types
- *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.
- *- *-var myStore = new Ext.data.ArrayStore({ - fields: ['fullname', 'first'], - idIndex: 0 // id for each record will be the first element -}); - *For custom implementations create a basic {@link Ext.data.Store} configured as needed:
- *- *-// 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 - ) -}); - *Load some data into store (note the data object is an array which corresponds to the reader):
- *- *-var myData = [ - [1, 'Fred Flintstone', 'Fred'], // note that id for the record is the first element - [2, 'Barney Rubble', 'Barney'] -]; -myStore.loadData(myData); - *Records are cached and made available through accessor functions. An example of adding - * a record to the store:
- *- *-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}) - *Writing Data
- *And new in Ext version 3, use the new {@link Ext.data.DataWriter DataWriter} to create an automated, Writable Store - * along with RESTful features. - * @constructor - * Creates a new Store. - * @param {Object} config A config object containing the objects needed for the Store to access data, - * and read the data into Records. - * @xtype store +
