Returns:

the current reference count

release

void release()

Signal the resource that a previous hold is complete

releaseAndCount

long releaseAndCount()

Signal the resource that a previous hold is complete.

Returns:

the current reference count

getReferenceCount

long getReferenceCount()

Number of active references

Returns:

current reference count
