Examples of ptolemy.data.ScalarToken.absolute()

ptolemy.data.ScalarToken.absolute()

Return a ScalarToken containing the absolute value of the value of this token. If this token contains a non-negative number, it is returned directly; otherwise, a new token is returned. Note that it is explicitly allowable to return this token, since the units are the same. This method defers to the _absolute() method to perform the operation, and derived classes should implement that method to provide type-specific behavior. @return A ScalarToken with the same units, and likely to be ofthe same type as this token. If this token is a nil token, then {@link ptolemy.data.Token#NIL}is returned.
