Next snippet Consequently, choice is used to realize a dynamic conditional branch. It allows splitting of compound transitions into multiple alternative paths such that the decision on which path to take may depend on the results of Behavior executions performed ... Related snippets junction – This type of Pseudostate is used to connect multiple Transitions into compound paths between States.
