21/**
22 * Delegate implementing the native methods of android.graphics.DashPathEffect
23 *
24 * Through the layoutlib_create tool, the original native methods of DashPathEffect have been
25 * replaced by calls to methods of the same name in this delegate class.
26 *
27 * This class behaves like the original native implementation, but in Java, keeping previously
28 * native data into its own objects and mapping them to int that are sent back and forth between
29 * it and the original DashPathEffect class.
30 *
31 * Because this extends {@link PathEffect_Delegate}, there's no need to use a
32 * {@link DelegateManager}, as all the PathEffect classes will be added to the manager owned by
33 * {@link PathEffect_Delegate}.
