Methods

Public Instance methods

Registers a callback for the event on the object. The callback can either be a block or a proc. When the callbacks are notified, the return value of the proc is passed to the caller.

[Source]

   # File lib/spec/callback/extensions/object.rb, line 5
5:     def register_callback(event, callback_proc=nil, &callback_block)
6:       callbacks.define(event, callback_proc, &callback_block)
7:     end

Removes the callback from the event. The callback proc must be the same object as the one that was passed to register_callback.

    # File lib/spec/callback/extensions/object.rb, line 11
11:     def unregister_callback(event, callback_proc)
12:       callbacks.undefine(event, callback_proc)
13:     end

Protected Instance methods

The CallbackContainer for this object.

    # File lib/spec/callback/extensions/object.rb, line 25
25:     def callbacks
26:       @callbacks ||= CallbackContainer.new
27:     end

Notifies the callbacks registered with the event on the object. Arguments can be passed to the callbacks. An error handler may be passed in as a block. If there is an error, the block is called with error object as an argument. An array of the return values of the callbacks is returned.

    # File lib/spec/callback/extensions/object.rb, line 20
20:     def notify_callbacks(event, *args, &error_handler)
21:       callbacks.notify(event, *args, &error_handler)
22:     end
