History Element (State Machine Diagrams)
Go Up to UML 2.0 State Machine Diagrams Index
The Shallow History and Deep History elements are placed on regions of the states.
There may be none or one Deep History, and none or one Shallow History elements in each region. If there is only one history element in a region, it may be switched from the Deep to Shallow type by changing its kind property.
Please refer to UML 2.0 Specification for more information about these elements.
