Method Details

canRetain

public boolean canRetain()

Description copied from interface: Retainable

Returns whether this resource is referenced counted by calls to Retainable.retain() and Retainable.release().

Implementations may decide that special resources are not not referenced counted (for example, static constants) so calling Retainable.retain() is a no-operation, and calling Retainable.release() on those special resources is a no-operation that always returns true.

Returns:

true if calls to Retainable.retain() are reference counted.

retain

public void retain()

Description copied from interface: Retainable

Retains this resource, potentially incrementing a reference count if there are resources that will be released.

release

public boolean release()

Description copied from interface: Retainable

Releases this resource, potentially decrementing a reference count (if any).

Returns:

true when the reference count goes to zero or if there was no reference count, false otherwise.

toString

public String toString()

Overrides:
