Class fmHyperlinkRouter

java.lang.Object
  com.fm.gui.fmHyperlinkRouter

All Implemented Interfaces:: java.util.EventListener, javax.swing.event.HyperlinkListener

public class fmHyperlinkRouter
extends java.lang.Object
implements javax.swing.event.HyperlinkListener

Entities of class handle hyperlink events within GUI components.

The fmHyperlinkRouter serves as a hyperlink event router. Entities of the class handle link update event, then scan own table of prefix handlers and if URL starts with one of prefixes defined in this table the event is routed to appropriate prefix handler handler. If no prefix handler is defined the URL will be served by external or internal browser respectively.

The prefix handler is a HyperLinkListener entity, which performs some specific operations with link which starts with handler specific prefix.

It's assumed that only one handler for the prefix exists in the router configuration. This is done to avoid overlapped actions of handlers of the same type
