public class Xfermode
extends Object

Xfermode is the base class for objects that are called to implement custom "transfer-modes" in the drawing pipeline. The static function Create(Modes) can be called to return an instance of any of the predefined subclasses as specified in the Modes enum. When an Xfermode is assigned to an Paint, then objects drawn with that paint have the xfermode applied.

finalize

protected void finalize()
                 throws Throwable

Description copied from class: Object

Called by the virtual machine when there are no longer any (non-weak) references to the receiver. Subclasses can use this facility to guarantee that any associated resources are cleaned up before the receiver is garbage collected. Uncaught exceptions which are thrown during the running of the method cause it to terminate immediately, but are otherwise ignored.

Note: The virtual machine assumes that the implementation in class Object is empty.

Overrides:

finalize in class Object

Throws:

Throwable - The virtual machine ignores any exceptions which are thrown during finalization.
