Class DelegatingThemeDefinition

  • All Implemented Interfaces:
    ThemeDefinition

    public class DelegatingThemeDefinition
    extends java.lang.Object
    implements ThemeDefinition
    Allows you to more easily wrap an existing theme definion and alter the behaviour in some special cases. You normally create a new class that extends from this and override some of the methods to divert the call depending on what you are trying to do. For an example, please see Issue409 in the test code.
