MTLFence object is typically used to track a sub-allocated resource created from a
MTLHeap object. However, it can also track a non-heap resource that specifies a
hazard resource option.
Don’t implement this protocol yourself; instead, to create a
MTLFence object, call the
make method of a
MTLDevice object. A command encoder can either update a fence or wait for a fence. Refer to the methods listed in the following table for further information.
