Method Detail

checkOut

public void checkOut()
              throws java.io.IOException

Description copied from interface: MutableArea

Checks out all changes made to this area. This should be called after a series of updates have been made to the area and the final change is to be 'finalized'. When this method returns, any new Area or MutableArea objects created by the backing store will contain the changes made to this object. Any changes made to the Area may or may not be made to any already existing areas.

In a logging implementation, this may flush out the changes made to the area in a log.
