Class ProxyIncrLayout

  • All Implemented Interfaces:
    GlobalLayout, IncrementalLayout
    public class ProxyIncrLayout
extends java.lang.Object
implements IncrementalLayout
    A proxy layout which forwards all events to a given incremental layout delegate. This class implements the proxy design pattern, hence its name. It is a useful base class for building layouts that know how to do a certain specific task, but want to delegate work to a more general layout for the cases that it doesn't know how to deal with.
