| Known Direct Subclasses
AutoRotateDrawable, InstrumentedDrawable, MatrixDrawable, OrientedDrawable, RootDrawable, RoundedCornersDrawable, ScaleTypeDrawable
| AutoRotateDrawable | Drawable that automatically rotates underlying drawable. |
| InstrumentedDrawable | Used to log image params at draw-time. |
| MatrixDrawable | Drawable that can adjust underlying drawable based on specified Matrix. |
| OrientedDrawable | Drawable that automatically rotates the underlying drawable with a pivot in the center of the drawable bounds based on a rotation angle. |
| RootDrawable | The root drawable of a DraweeHierarchy. |
| RoundedCornersDrawable | Drawable that draws underlying drawable with rounded corners. |
| ScaleTypeDrawable | Drawable that can scale underlying drawable based on specified ScalingUtils.ScaleType options. |
|
A forwarding drawable class - the goal is to forward (delegate) drawable functionality to an inner drawable instance. ForwardingDrawable intercepts the public (and protected) methods of Drawable, maintains local state if needed.
Design note: It would have been very helpful to re-use Android library classes like DrawableContainer, LevelListDrawable etc. DrawableContainer is not directly subclassable, and the others don't allow changing the member drawables.

|
Constructs a new forwarding drawable.
| drawable | drawable that this forwarding drawable will forward to |
Gets the child drawable.
Called when the drawable needs to get its root bounds.
| bounds | The root bounds of the drawable. |
Called when the drawable needs to get all matrices applied to it.
| transform | Matrix that is applied to the drawable by the parent drawables. |
Gets the transformed bounds of this drawable. Note: bounds are not cropped (otherwise they would likely be the same as drawable's bounds).
| outBounds | rect to fill with bounds |
Sets a new drawable to be the delegate, and returns the old one (or null).
This method will cause the drawable to be invalidated.
Sets the new child drawable.
| newDrawable | a new child drawable to set |
Sets a transform callback.
| transformCallback | the transform callback to be set |
As setCurrent, but without invalidating a drawable. Subclasses are responsible to call invalidateSelf on their own.
