Otherwise, the appropriate history entry into the Region is executed (see above). If no default history Transition is defined, then standard default entry of the Region is performed .... Source Unified Modeling Language 2.5.1
This is a Transition that originates in the history Pseudostate and terminates on a specific Vertex (the default history state) of the Region containing the history Pseudostate. This Transition is only taken if execution leads to the history Pseudostate a Source Unified Modeling Language 2.5.1
In cases where a Transition terminates on a history Pseudostate when the State has not been entered before (i.e., no prior history) or it had reached its FinalState, there is an option to force a transition to a specific substate, using the default ... Source Unified Modeling Language 2.5.1
Shallow history (shallowHistory) represents a return to only the topmost substate of the most recent state configuration, which is entered using the default entry rule. Source Unified Modeling Language 2.5.1
The effect is the same as if the Transition terminating on the deepHistory Pseudostate had, instead, terminated on the innermost State of the preserved state configuration, including execution of all entry Behaviors encountered along the way. Source Unified Modeling Language 2.5.1
Deep history (deepHistory) represents the full state configuration of the most recent visit to the containing Region. Source Unified Modeling Language 2.5.1
