Class EventMachine::Channel
In: lib/em/channel.rb
Parent: Object

Provides a simple interface to push items to a number of subscribers. The channel will schedule all operations on the main reactor thread for thread safe reactor operations.

This provides a convenient way for connections to consume messages from long running code in defer, without threading issues.

 channel = EM::Channel.new
 sid = channel.subscribe{ |msg| p [:got, msg] }
 channel.push('hello world')
 channel.unsubscribe(sid)

See examples/ex_channel.rb for a detailed example.
