Instance Method Details

#create(*args, &block) ⇒ Object

allows for easier construction of a user callback block that will be called with the callback object itself as an argument.

*args, if given, will be passed on after the callback

example:

WatcherCallback.create do |cb|
  puts "watcher callback called with argument: #{cb.inspect}"
end

"watcher callback called with argument: #<ZookeeperCallbacks::WatcherCallback:0x1018a3958 @state=3, @type=1, ...>"
