      • apply

        boolean apply​(@Nullable
                      T input)
        Returns the result of applying this predicate to input. 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)).
        Throws:
        java.lang.NullPointerException - if input is null and this predicate does not accept null arguments
      • equals

        boolean equals​(@Nullable
                       java.lang.Object object)
        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.

        Overrides:
        equals in class java.lang.Object
