  13  * @class Roo.data.JsonReader
  14  * @extends Roo.data.DataReader
  15  * Data reader class to create an Array of Roo.data.Record objects from a JSON response
  16  * based on mappings in a provided Roo.data.Record constructor.
  17  *
  18  * The default behaviour of a store is to send ?_requestMeta=1, unless the class has recieved 'metaData' property
  19  * in the reply previously.
  20  *
  21  * &lt;p&gt;
  22  * Example code:
  23  * &lt;pre&gt;&lt;code&gt;
  24 var RecordDef = Roo.data.Record.create([
  25     {name: 'name', mapping: 'name'},     // &quot;mapping&quot; property not needed if it's the same as &quot;name&quot;
  26     {name: 'occupation'}                 // This field will use &quot;occupation&quot; as the mapping.
  27 ]);
  28 var myReader = new Roo.data.JsonReader({
  29     totalProperty: &quot;results&quot;,    // The property which contains the total dataset size (optional)
  30     root: &quot;rows&quot;,                // The property which contains an Array of row objects
  31     id: &quot;id&quot;                     // The property within each row object that provides an ID for the record (optional)
  32 }, RecordDef);
  33 &lt;/code&gt;&lt;/pre&gt;
  34  * &lt;p&gt;
  35  * This would consume a JSON file like this:
  36  * &lt;pre&gt;&lt;code&gt;
  37 { 'results': 2, 'rows': [
  38     { 'id': 1, 'name': 'Bill', occupation: 'Gardener' },
  39     { 'id': 2, 'name': 'Ben', occupation: 'Horticulturalist' } ]
  40 }
  41 &lt;/code&gt;&lt;/pre&gt;
  42  * @cfg {String} totalProperty Name of the property from which to retrieve the total number of records
  43  * in the dataset. This is only needed if the whole dataset is not passed in one go, but is being
  44  * paged from the remote server.
  45  * @cfg {String} successProperty Name of the property from which to retrieve the success attribute used by forms.
  46  * @cfg {String} root name of the property which contains the Array of row objects.
  47  * @cfg {String} id Name of the property within a row object that contains a record identifier value.
  48  * @cfg {Array} fields Array of field definition objects
  49  * @constructor
  50  * Create a new JsonReader
  51  * @param {Object} meta Metadata configuration options
  52  * @param {Object} recordType Either an Array of field definition objects,
  53  * or an {@link Roo.data.Record} object created using {@link Roo.data.Record#create}.
