All Implemented Interfaces:

java.io.Serializable, Visitable

public class AndBinary<T1,T2>
extends BinaryFunctor<T1,T2,java.lang.Boolean>

Binary that performs a shortcircuit and operation using a given pair of Boolean BinaryFunctors. When the first functor returns true, the second is not evaluated.
