Class Matrix_Delegate



  • public final class Matrix_Delegate
    extends Object
    Delegate implementing the native methods of android.graphics.Matrix Through the layoutlib_create tool, the original native methods of Matrix have been replaced by calls to methods of the same name in this delegate class.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 Matrix class.
