Class Ext.data.ArrayReader

Package:	Ext.data
Class:	ArrayReader
Extends:	Ext.data.DataReader
Defined In:	ArrayReader.js

Data reader class to create an Array of Ext.data.Record objects from an Array. Each element of that Array represents a row of data fields. The fields are pulled into a Record object using as a subscript, the mapping property of the field definition if it exists, or the field's ordinal position in the definition.

Example code:.

var RecordDef = Ext.data.Record.create([
    {name: 'name', mapping: 1},         // "mapping" only needed if an "id" field is present which
    {name: 'occupation', mapping: 2}    // precludes using the ordinal position as the index.
]);
var myReader = new Ext.data.ArrayReader({
    id: 0                     // The subscript within row Array that provides an ID for the Record (optional)
}, RecordDef);

This would consume an Array like this:

[ [1, 'Bill', 'Gardener'], [2, 'Ben', 'Horticulturalist'] ]
