acceptable class for the container.NameDuplicationException - If the name coincides with
a parameter already in the container.protected void _evaluate(Pattern pattern, MatchResult matchResult) throws IllegalActionException
GTParameter.Evaluator. If this variable
was last set directly with a token, then do nothing. In other words,
the expression is evaluated only if the value of the token was most
recently given by an expression. The expression is also evaluated
if any of the variables it refers to have changed since the last
evaluation. If the value of this variable
changes due to this evaluation, then notify all
value dependents and notify the container (if there is one) by
calling its attributeChanged() and attributeTypeChanged() methods,
as appropriate. An exception is thrown
if the expression is illegal, for example if a parse error occurs
or if there is a dependency loop.
If evaluation results in a token that is not of the same type as the current type of the variable, then the type of the variable is changed, unless the new type is incompatible with statically specified types (setTypeEquals() and setTypeAtMost()). If the type is changed, the attributeTypeChanged() method of the container is called. The container can reject the change by throwing an exception.
This method may trigger a model error, which is delegated up the container hierarchy until an error handler is found, and is ignored if no error handler is found. A model error occurs if the expression cannot be parsed or cannot be evaluated.
Part of this method is read-synchronized on the workspace.
pattern - The pattern.matchResult - The match result for the match between the pattern
and a host model.IllegalActionException - If the expression cannot
be parsed or cannot be evaluated, or if a dependency loop is found.
