Deep History Pseudostate

Owning Palette: Statechart Development Objects

Requires: Statechart Module

Specifies that, when the statechart leaves and then returns to a region, the statechart enters the lowest-level substates that were active when the statechart left the region.

To use the Deep History pseudostate, place this pseudostate in a region and then create a transition from a state to this pseudostate.

Note  You use this pseudostate in Part 5 of the Getting Started tutorial.

Add to the statechart diagram

Find on the palette

Note  Statechart history is erased after the statechart terminates.

You can create multiple incoming transitions to this pseudostate, but you cannot create any outgoing transitions from this pseudostate.

The Deep History pseudostate returns to the lowest-level substates that were active when the statechart left the region. To return to the highest-level substates, use the Shallow History pseudostate.
