Class Gui4jMap1

java.lang.Object
  org.gui4j.core.Gui4jMap1

All Implemented Interfaces:: java.util.Map, java.util.Map.Entry, java.io.Serializable

public final class Gui4jMap1
extends java.lang.Object
implements java.util.Map, java.util.Map.Entry, java.io.Serializable

The class Gui4jAccess works with parameter maps. Since usually only one parameter is used, this class provides a very simple implementation of the Map interface for exaclty one entry. Note that this class is only to improve performance.
