Construct an iterator for all of the rectangles in a region.
Return the next rectangle in the region.
Called before the object's memory is reclaimed by the VM.
From class java.lang.Object
Construct an iterator for all of the rectangles in a region. This effectively makes a private copy of the region, so any subsequent edits to region will not affect the iterator.
|region||the region that will be iterated|
Return the next rectangle in the region. If there are no more rectangles this returns false and r is unchanged. If there is at least one more, this returns true and r is set to that rectangle.
Called before the object's memory is reclaimed by the VM. This can only happen once the garbage collector has detected that the object is no longer reachable by any thread of the running application.
The method can be used to free system resources or perform other cleanup
before the object is garbage collected. The default implementation of the
method is empty, which is also expected by the VM, but subclasses can
finalize() as required. Uncaught exceptions which are
thrown during the execution of this method cause it to terminate
immediately but are otherwise ignored.
Note that the VM does guarantee that
finalize() is called at most
once for any object, but it doesn't guarantee when (if at all)
finalize() will be called. For example, object B's
can delay the execution of object A's
finalize() method and
therefore it can delay the reclamation of A's memory. To be safe, use a
ReferenceQueue, because it provides more control
over the way the VM deals with references during garbage collection.
