Class JHelpContextMgr

java.lang.Object
  com.jstatcom.component.JHelpContextMgr

public final class JHelpContextMgr
extends java.lang.Object

Manages the mapping between IDs for context sensitive help topics and the respective components. The mapping is stored in an XML file help_context.xml. Components that should use context sensitive help must register with the JHelpContextMgr. This class is used to maintain all help IDs in a single place that can be edited without changing the code. Components are identified via their classname.
