      • apply

        public boolean apply​(T input)
        Description copied from interface: Predicate
        Returns the result of applying this predicate to input (Java 8 users, see notes in the class documentation above). This method is generally expected, but not absolutely required, to have the following properties:
        • Its execution does not cause any observable side effects.
        • The computation is consistent with equals; that is, Objects.equal(a, b) implies that predicate.apply(a) == predicate.apply(b)).
        Specified by:
        apply in interface Predicate<T>

      • equals

        public boolean equals​(java.lang.Object obj)
        Description copied from interface: Predicate
        Indicates whether another object is equal to this predicate.

        Most implementations will have no reason to override the behavior of Object.equals(java.lang.Object). However, an implementation may also choose to return true whenever object is a Predicate that it considers interchangeable with this one. "Interchangeable" typically means that this.apply(t) == that.apply(t) for all t of type T). Note that a false result from this method does not imply that the predicates are known not to be interchangeable.
