virtual void MgLayerBase::SetLayerDefinition	(	MgResourceIdentifier *	layerDefinition,
		MgResourceService *	resourceService
	)		[virtual]

Sets the the layer definition for this layer.

Remarks:

This method can be used to alter the definition of a layer, including the layer's data source definition or stylization rules. For example to change the Filter used to retrieve features on a FeatureLayer, the old definition can be retrieved, altered, and stored in the session repository. Then the SetLayerDefinition method can be called with the ResourceId of the altered layer definition in the session repository.

From 2.7 onwards, this method will no longer modify the layer name. Previous versions will set the layer's name based on the name of the Layer Definition resource ID

Note:

If you change the layer's definition, you must also change the cached scale ranges and force an update of any layer metadata held in the DWF Viewer's eMap.
