cancel_process
Cancels a whole process instance.
pdef = Ruote.process_definition :name => 'test' do
sequence do
participant :ref => 'editor'
concurrence do
participant :ref => 'reviewer1'
participant :ref => 'reviewer2'
sequence do
participant :ref => 'main_reviewer'
cancel_process :if => '${f:over} == true'
end
end
participant :ref => 'editor'
end
end
This example has a ‘main_reviewer’ with the ability to cancel the whole
process, if he sets the workitem field ‘over’ to ‘true’.
If the goal is to cancel only a segment of a process instance, the
expression ‘undo’ (Ruote::Exp::UndoExpression) is better suited.
‘terminate’
Sometimes ‘terminate’ reads better than ‘cancel_process’
Ruote.process_definition do
alice :task => 'do this'
terminate :if => '${no_need_for_bob}'
bob :task => 'do that'
charly :task => 'just do it'
end
