Method Summary
`boolean` | `apply(T input)` Returns the result of applying this predicate to `input`.
`boolean` | `equals(Object object)` Indicates whether another object is equal to this predicate.

Method Detail

### 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:
    `NullPointerException` - if `input` is null and this predicate does not accept null arguments

### equals

    boolean equals(@Nullable
                   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 `Object`
