Class Exceptions

java.lang.Object
  ch.elca.el4j.services.gui.swing.exceptions.Exceptions

All Implemented Interfaces:

Thread.UncaughtExceptionHandler

public final class Exceptions
extends Object
implements Thread.UncaughtExceptionHandler

This Exception Handler Manager allows to register Exception Handlers. If an uncaught exception occurs, the handlers get executed in the order of their priority until a handler signals that no further handler should be called (handle() return true). In case that no handlers get executed, a stack trace will be printed to std err.
