Shader_Delegate

public abstract class Shader_Delegate extends Object
Delegate implementing the native methods of android.graphics.Shader Through the layoutlib_create tool, the original native methods of Shader have been replaced by calls to methods of the same name in this delegate class. This class behaves like the original native implementation, but in Java, keeping previously native data into its own objects and mapping them to int that are sent back and forth between it and the original Shader class. This also serve as a base class for all Shader delegate classes.
