Class ProgressListenerFactory

java.lang.Object

at.tuwien.ifs.somtoolbox.util.ProgressListenerFactory

public class ProgressListenerFactory
extends java.lang.Object

A singleton factory creating ProgressListeners. If an instance of a ProgressListener is set, this instance is returned instead of creating a new one. This allows calling applications to set their own ProgressListener, while preserving backwards compatibility.
