    Description

    Stateflow.SymbolReference objects indicate where a Stateflow® chart refers to a symbol name. For example, a Stateflow.SymbolReference object can correspond to a state or transition action that includes a symbol name. Symbols include Stateflow.Data, Stateflow.Event, Stateflow.Message, and other Stateflow objects that have a Name property.

    Creation

    The Stateflow chart maintains an array of Stateflow.SymbolReference objects for each symbol. To access this array, call the object function getReferences.
