Constructor Detail

ManagedReference

public ManagedReference(T actualRef,
                        Predicate<T> retainVerifier,
                        Consumer<T> deallocator)

Parameters:

actualRef -

retainVerifier - Called with "actualRef" as the parameter before returning from retain() or retain(int). If false is returned, then the "retain" method throws an IllegalReferenceCountException.

deallocator - Called automatically only when the AbstractReferenceCounted.refCnt() drops to 0 with "actualRef" as the parameter.
