Class OpenWFE::ProcessParticipant

Links a process under a participant [name].

Turns top level processes into participants

Some examples :

require 'engine/participants/participants'

engine.register_participant(
  "transmit_to_accounting",
  "http://company.process.server.ie/processes/acc0.xml")

engine.register_participant(
  "hr_resume_review_process",
  "file:/var/processes/hr_resume_review_process.rb")

Some more examples :

class RegistrationProcess < OpenWFE::ProcessDefinition
  sequence do
    participant :ref => "Alice"
    participant :ref => "Bob"
  end
end

# later in the code ...

engine.register_participant("registration", RegistrationProcess)

Or directly with some XML string :

engine.register_participant("registration", '''
  <process-definition name="registration" revision="0.1">
    <sequence>
      <participant ref="Alice" />
      <participant ref="Bob" />
    </sequence>
  </process-definition>
'''.strip)

It’s then easy to call the subprocess as if it were a participant :

sequence do
  participant :ref => "registration"
    # or
  participant "registration"
    # or simply
  registration
end

Note that the ‘subprocess’ expression may be used as well :

sequence do
  subprocess ref => "http://dms.company.org/processes/proc1.rb"
end

But you can’t use the URL as an expression name for writing nice, concise, process definitions.
