A StateMachine instance never comes to rest in a Pseudostate, instead, it will exit and enter the Pseudostate within a single run-to-completion step. Next snippet Related snippets 14.2.3.5 ConnectionPointReference ... a connection point reference represents a usage (as part of a submachine State) of an entry/exit point defined in the StateMachine referenced by the submachine State. initial - An initial Pseudostate represents a starting point for a Region; that is, it is the point from which execution of its contained behavior commences when the Region is entered via default activation. join – This type of Pseudostate serves as a common target Vertex for two or more Transitions originating from Vertices in different orthogonal Regions. fork – fork Pseudostates serve to split an incoming Transition into two or more Transitions terminating on Vertices in orthogonal Regions of a composite State. junction – This type of Pseudostate is used to connect multiple Transitions into compound paths between States. choice – This type of Pseudostate is similar to a junction Pseudostate ... and serves similar purposes, with the difference that the guard Constraints on all outgoing Transitions are evaluated dynamically ... entryPoint – An entryPoint Pseudostate represents an entry point for a StateMachine or a composite State that provides encapsulation of the insides of the State or StateMachine. exitPoint – An exitPoint Pseudostate is an exit point of a StateMachine or composite State that provides encapsulation of the insides of the State or StateMachine. deepHistory – This type of Pseudostate is a kind of variable that represents the most recent active state configuration of its owning Region. ... a Transition terminating on this Pseudostate implies restoring the Region to that same state ... shallowHistory – ... this type of Pseudostate is a kind of variable that represents the most recent active substate of its containing Region, but not the substates of that substate. A Transition terminating on this Pseudostate implies rest terminate – Entering a terminate Pseudostate implies that the execution of the StateMachine is terminated immediately. The StateMachine does not exit any States nor does it perform any exit Behaviors. Any executing doActivity Behaviors are ... aborted Related snippets (backlinks) Visit also Visit also (backlinks) Flags
