GlobalErrorHandler

Interface to setting up a handler for any uncaught exceptions in the application. The block that is passed into GlobalErrorHandler.on_error will be called when an uncaught exception occurs.

You must be VERY careful when implementing your handler. All uncaught exceptions will be routed to this block so any error that occur inside the block will not generate exceptions.

on_error(&callback) click to toggle source

Creation point for the GlobalErrorHandler. To use, pass in a block that takes 2 parameters, the exception and the thread that the exception occured on.

The exception passed into this block is a Java Throwable, not a Ruby exception. java.sun.com/j2se/1.5.0/docs/api/java/lang/Throwable.html

GlobalErrorHandler.on_error {|exception, thread| puts "Error #{exception} occured on thread #{thread}" }

or you may want to dispatch to an error handler method.

GlobalErrorHandler.on_error {|exception, thread| my_error_handler_method(exception, thread) }

# File lib/monkeybars/global_error_handler.rb, line 22
def self.on_error(&callback)
  java.lang.Thread.default_uncaught_exception_handler = self.new(&callback)
end
