Ext.data.reader.ReaderExt.data.reader.JsonExt.data.reader.Array
Data reader class to create an Array of Ext.data.Model 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:
Employee = Ext.define('Employee', {
extend: 'Ext.data.Model',
fields: [
'id',
{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.reader.Array({
model: 'Employee'
}, Employee);
This would consume an Array like this:
[ [1, 'Bill', 'Gardener'], [2, 'Ben', 'Horticulturalist'] ]
Name of the property within a row object that contains a record identifier value. Defaults to The id of the model. If an idProperty is explicitly specified it will override that of the one specified on the model
True to automatically parse models nested within other models in a response object. See the Ext.data.reader.Reader intro docs for full explanation. Defaults to true.
The name of the property which contains a response message. This property is optional.
The name of the property which contains a response message. This property is optional.
The optional location within the JSON response that the record data itself can be found at. See the JsonReader intro docs for more details. This is not often needed and defaults to undefined.
Required. The name of the property which contains the Array of row objects. Defaults to undefined. An exception will be thrown if the root property is undefined. The data packet value for this property should be an empty array to clear the data or show no data.
Name of the property from which to retrieve the success attribute. Defaults to success. See Ext.data.proxy.Proxy.exception for additional information.
Name of the property from which to retrieve the total number of records in the dataset. This is only needed if the whole dataset is not passed in one go, but is being paged from the remote server. Defaults to total.
True to ensure that field names/mappings are treated as literals when reading values. Defalts to false. For example, by default, using the mapping "foo.bar.baz" will try and read a property foo from the root, then a property bar from foo, then a property baz from bar. Setting the simple accessors to true will read the property with the name "foo.bar.baz" direct from the root object.

Metadata configuration options.
Takes a raw response object (as passed to this.read) and returns the useful data segment of it. This must be implemented by each subclass
The responce object
The useful data from the response
Reads the given response object. This method normalizes the different types of response object that may be passed to it, before handing off the reading of records to the readRecords function.
The response object. This may be either an XMLHttpRequest object or a plain JS object
The parsed ResultSet object
Reads a JSON object and returns a ResultSet. Uses the internal getTotal and getSuccess extractors to retrieve meta data from the response, and extractData to turn the JSON data into model instances.
The raw JSON data
A ResultSet containing model instances and meta data about the results
