ptolemy.data.expr.TemporaryVariable

This is identical to a Variable except that creating it does not increment the workspace version. It should be used to create a variable to store information and make that information visible to the user, but where the presence of this variable has no bearing on type resolution, scheduling, model structure, or any other property of the model that might invalidate cached information. This variable should be used with caution, but use of this variable can significantly improve performance since it makes caching of information that is expensive to compute much more effective. @author Edward A.
