====== The Concepts : Action Step ======

The Action Step is used to map a method definition to a flow chain of execution. It is very simple and does not take much parameters. Read the [[http://actionflow.devdonkey.org/rdoc-head/classes/ActionFlow/ActionStep.html|Action Step API]] for more details.

<code ruby>
class MyController < ActionFlow::Base

  def initialize

    # Map an action step
    action_step :my_step do

      on :event_name => :next_step_name

      # Use the superclass 'method' instruction to map the method named
      # 'my_step_implementation_method' as this step implementation.
      # This is optionnal since by default, it would search for a method
      # named after the step name : 'my_step'
      method :my_step_implementation_method

    end

    (...)

  end

  def my_step_implementation_method

    # Return an event
    event :event_name

  end

  (...)

end
</code>

The standard [[Flow Step]] superclass methods are also available.
