Examples of ptolemy.data.BooleanToken

ptolemy.data.BooleanToken
A token that contains a boolean variable. Arithmetic on booleans is that of a two-element Galois field (modulo two arithmetic). Thus, add() is logical xor, multiply() is logical and, zero() is false, one() is true.
In order to reduce the number of instances of this object that are created, it is highly recommended that the getInstance() method be used, instead of the constructor that takes a boolean argument. @author Neil Smyth, Yuhong Xiong, Edward A.
