Class Ruote::BlockParticipant
In: lib/ruote/part/block_participant.rb
Parent: Object

One of the simplest participants. Simply passes a workitem to a block of ruby code.

  engine.register_participant :alpha do |workitem|
    workitem.fields['time'] = Time.now
  end

This participant implicitely replies to the engine when the block execution is over.

You can pass the flow_expression (participant expression) as well.

  engine.register_participant :alpha do |workitem, flow_exp|
    workitem.fields['amount'] = flow_exp.lookup_variable('amount')
  end

do_not_thread

By default, this participant (like most other participants) is executed in its own thread.
