        public InequalityTerm getTypeTerm​(java.lang.String name)
                           throws IllegalActionException
        Look up and return the type term for the specified name in the scope. Return null if the name is not defined in this scope, or is a constant type.

      • identifierSet

        public java.util.Set<java.lang.String> identifierSet()
                                              throws IllegalActionException
        Return a list of names corresponding to the identifiers defined by this scope. If an identifier is returned in this list, then get() and getType() will return a value for the identifier. Note that generally speaking, this list is extremely expensive to compute, and users should avoid calling it. It is primarily used for debugging purposes.
        Returns:
        A list of names corresponding to the identifiers defined by this scope.
        Throws:
        IllegalActionException - If constructing the list causes it.
