Examples of ptolemy.data.StringToken

ptolemy.data.StringToken
A token that contains a string, or more specifically, a reference to an instance of String. The reference is never null, although it may be an empty string (""). Note that when this token is cloned, the clone will refer to exactly the same String object. However, a String object in Java is immutable, so there is no risk when two tokens refer to the same string that one of the strings will be changed. @author Edward A.
