Method: ActionCable::Channel::Base#perform_action

Defined in:
actioncable/lib/action_cable/channel/base.rb

#perform_action(data) ⇒ Object

Extract the action name from the passed data and process it via the channel. The process will ensure that the action requested is a public method on the channel declared by the user (so not one of the callbacks like #subscribed).
