Identifying, characterizing, and naming object states is a necessary step in the creation of Op State Transition descriptions.
The following properties apply when defining an Object State Symbol:
Glossary
A textual description, or glossary, associated with the Object Schematic. Any descriptive information that does not logically fit into the other fields in the document can be placed here.
Object Name
The name of the Object.
Object State Set
The set of object states that make up the state transition represented by the diagram.
Entry Condition Sets
Entry From State
States that the object is in before it enters the current state.
Entry From Facts
Facts that are true when the object enters the current state.
Entry From Constraints
Constraints on the object entering the current state.
State Description Conditions
Facts
Noteworthy, nonconstraining facts involving the objects that participate in the relationship represented by the dashed link.
Constraints
Noteworthy constraints that hold between the source and destination elements or between some of their constituent objects.
Exit Condition Sets
Exit To State
States that the object will be in after it leaves the current state.
Exit To Facts
Facts that are true when the object leaves the current state.
Exit To Constraints
Constraints on the object leaving the current state.
