Workflow Control Pattern 29 - Cancelling Discriminator
2011-10-04 20:52:47 1 举报
The convergence of two or more branches into a single subsequent branch following one or more corresponding divergences earlier in the process model. The thread of control is passed to the subsequent branch when the first active incoming branch has been enabled. Triggering the Cancelling Discriminator also cancels the execution of all of the other incoming branches and resets the construct.
