Constructor Detail

RegionIterator

public RegionIterator(Region region)

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.

Parameters:

region - the region that will be iterated

Method Detail

next

public final boolean next(Rect r)

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.

finalize

protected void finalize()
                 throws Throwable

Description copied from class: Object

Called by the virtual machine when there are no longer any (non-weak) references to the receiver. Subclasses can use this facility to guarantee that any associated resources are cleaned up before the receiver is garbage collected. Uncaught exceptions which are thrown during the running of the method cause it to terminate immediately, but are otherwise ignored.

Note: The virtual machine assumes that the implementation in class Object is empty.

Overrides:

finalize in class Object

Throws:

Throwable - The virtual machine ignores any exceptions which are thrown during finalization.
