24/**
25 * Delegate implementing the native methods of android.graphics.ComposePathEffect
26 *
27 * Through the layoutlib_create tool, the original native methods of ComposePathEffect have been
28 * replaced by calls to methods of the same name in this delegate class.
29 *
30 * This class behaves like the original native implementation, but in Java, keeping previously
31 * native data into its own objects and mapping them to int that are sent back and forth between
32 * it and the original ComposePathEffect class.
33 *
34 * Because this extends {@link PathEffect_Delegate}, there's no need to use a {@link DelegateManager},
35 * as all the Shader classes will be added to the manager owned by {@link PathEffect_Delegate}.
