| * Delegate implementing the native methods of android.graphics.DashPathEffect |
| * |
| * Through the layoutlib_create tool, the original native methods of DashPathEffect 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 DashPathEffect class. |
| * |
| * Because this extends {@link PathEffect_Delegate}, there's no need to use a |
| * {@link DelegateManager}, as all the PathEffect classes will be added to the manager owned by |
| * {@link PathEffect_Delegate}. |
