class LittleGhost::Workflow::Invocation

Holds one lazy Assembly call inside a workflow composition. Read result for the child’s RunResult or output for its text or structured value. Either accessor runs the child once and reuses the result on later reads. Return this object from perform to select its result as the answer. Agent progress streams live independently of result access or selection.

Public Instance Methods

output ()

Source

# File lib/little_ghost/workflow.rb, line 131
def output = result.output

Returns the completed child’s text or structured value through RunResult#output. Runs the child when necessary, with the same progress behavior as result.

result ()

Source

# File lib/little_ghost/workflow.rb, line 117
def result
  unless consumed?
    each do |event|
      @owner.send(:emit_workflow_event, event) if event.type.to_s.start_with?("assembly_")
    end
  end
  raise ProtocolError, "workflow invocation has no completed result" unless @result

  @owner.send(:record_workflow_steps, @steps)
  @result
end

Runs this invocation when necessary and returns its completed RunResult.

Repeated reads reuse the same result without repeating work. Agent progress streams live regardless of how the result is accessed.
