new DataMapping()
Maps raw data to data objects of a specific type.
Currently services define their mapping by overriding their
mapRawDataToObject() and
mapObjectToRawData() methods or by
using a DataMapping subclass that overrides its
mapRawDataToObject() and
mapRawDataToObject() methods. In the
future it will be possible to define mappings declaratively through mapping
descriptors read from blueprint files.

Methods
mapRawDataToObject(object, data, context)
Convert raw data to data objects of an appropriate type.
Subclasses should override this method to map properties of the raw data
to data objects, as in the following:
mapRawDataToObject: {
value: function (object, data) {
object.firstName = data.GIVEN_NAME;
object.lastName = data.FAMILY_NAME;
}
}
The default implementation of this method copies the properties defined
by the raw data object to the data object.
Parameters:
Name | Type | Description |
---|---|---|
object |
Object | An object whose properties must be set or modified to represent the raw data. |
data |
Object | An object whose properties' values hold the raw data. |
context |
? | A value that was passed in to the addRawData() call that invoked this method. |
