| 25 | * Delegate implementing the native methods of android.graphics.ComposeShader |
| 26 | * |
| 27 | * Through the layoutlib_create tool, the original native methods of ComposeShader 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 ComposeShader class. |
| 33 | * |
| 34 | * Because this extends {@link Shader_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 Shader_Delegate}. |
| 36 | * |
| 37 | * @see Shader_Delegate |
