junction – ... If more than one guard evaluates to true, one of these is chosen. The algorithm for making this selection is not defined. Source Unified Modeling Language 2.5.1
(As a way of avoiding this situation in some cases, it is possible to associate a predefined guard denoted as “else” with at most one outgoing Transition. This Transition is enabled if all the guards attached to the other Transitions evaluate to false). Source Unified Modeling Language 2.5.1
junction – ...It may happen that, for a particular compound transition, the configuration of Transition paths and guard values is such that the compound transition is prevented from reaching a valid state configuration. In those cases, the entire ... Source Unified Modeling Language 2.5.1
NOTE. Such guard Constraints are evaluated before any compound transition containing this Pseudostate is executed, which is why this is referred to as a static conditional branch. Source Unified Modeling Language 2.5.1
.. a junction Pseudostate ... can be used to split an incoming Transition into multiple outgoing Transition segments with different guard Constraints. Source Unified Modeling Language 2.5.1
For example, a junction Pseudostate can be used to merge multiple incoming Transitions into a single outgoing Transition representing a shared continuation path. Source Unified Modeling Language 2.5.1
junction – This type of Pseudostate is used to connect multiple Transitions into compound paths between States. Source Unified Modeling Language 2.5.1
An entry point is equivalent to a junction Pseudostate (fork in cases where the composite State is orthogonal): Entering via an entry point implies that the entry Behavior of the composite state is executed, followed by the Transition from the entry ... Source Unified Modeling Language 2.5.1
