A minimalist pointer scope only keeping weak references to its elements.
As opposed to ERROR(/org.bytedeco.javacpp.PointerScope), instances of this class will not
prevent the garbage collector to free the memory of a pointer that is no longer reachable, even
if it has been attached to the scope.
When the scope is closed, all pointers that are still valid will be automatically deallocated while those already garbage-collected will be ignored.

Public Methods
public void attach (Pointer pointer)
Attach a pointer to this scope.
Pointers attached to the scope will be automatically freed once the scope is closed, unless they have been already released by the garbage collector
It this pointer was already attached to this scope, this method has no effect.
Parameters
| pointer | pointer to attach |
|---|
Throws
| IllegalStateException | if that scope has already been closed |
|---|
public synchronized void close ()
public void detach (Pointer pointer)
Detach a pointer from this scope.
Detaching a pointer from the scope will prevent its memory to be freed when closing the scope.
If this pointer is not attached to this scope, this method has no effect.
Parameters
| pointer | pointer to detach |
|---|
Throws
| IllegalStateException | if that scope has already been closed |
|---|
