Forgets all of its children.
This expression is somehow deprecated in favour of the :forget attribute
that any expression understands.
sequence do participant 'alpha' forget do sequence do participant 'bravo' participant 'charly' end end participant 'delta' end
In this example above, the flow goes from alpha to bravo and delta. The
bravo-charly segment is independent of the main process flow. Charly’s
reply will be forgotten.
Now the equivalent process definition, but using the :forget attribute :
sequence do participant 'alpha' sequence :forget => true do participant 'bravo' participant 'charly' end participant 'delta' end
This expression can be useful for fire-and-forget ‘parallelism’
Forget multiple children at once.
forget do alice :task => 'take out garbage' bob :task => 'clean living room' end
The forget expression will reply immediately to its parent expression, it
will thus not be cancellable (neither the children will be cancellable).
forget vs lose vs flank
forget : replies to parent expression immediately, is not cancellable
lose : never replies to the parent expression, is cancellable.
flank : immediately replies to the parent expression, is cancellable.
