Class CompositeErrorHandler

com.sas.util.errorhandlers.CompositeErrorHandler

All Implemented Interfaces:

ErrorHandlerInterface

public class CompositeErrorHandler
implements ErrorHandlerInterface

CompositeErrorHandler is a composite errorhandler. It is used to send error messages to two errorhandlers so that both can handle the error. An example of this is if an error should be put up in a messageBox and written to a log as well. To send error messages to more errorhandlers, use multiple CompositeErrorHandler objects:

 ErrorHandlerInterface fgh  = new CompositeErrorHandler(f, new CompositeErrorHandler(g, h));
 ErrorHandlerInterface fghi = new CompositeErrorHandler(new CompositeErrorHandler(f, g),
                                                  new CompositeErrorHandler(h, i));
