public class FrameRegister

extends java.util.HashMap

FrameRegister is a collection of ModuleFrames. It is an implementation of a simple monitor and it's purpose is to serialise the creation of new ModuleFrames. FrameRegister was written initially for the purpose of restoring saved windows as a way of accessing the new ModuleFrame objects but also as a way of serialising their creation. The use of some non thread safe objects were discovered when trying to create multiple ChartModules and the decision was made to serialise their creation under restoration rather than attempt to modify code that otherwise works perfectly well. This class is deprecated.
