Class Overview
This class provides several utilities to cancel bitmap decoding. The function decodeFileDescriptor() is used to decode a bitmap. During decoding if another thread wants to cancel it, it calls the function cancelThreadDecoding() specifying the Thread which is in decoding. cancelThreadDecoding() is sticky until allowThreadDecoding() is called. You can also cancel decoding for a set of threads using ThreadSet as the parameter for cancelThreadDecoding. To put a thread into a ThreadSet, use the add() method. A ThreadSet holds (weak) references to the threads, so you don't need to remove Thread from it if some thread dies.
