 * {@link PredicateTools} 用于 {@link java.util.function.Predicate} 的相关操作。

 *
 * <h2>Functional interfaces</h2>
 * <p>
 * 补充一些 JDK 没有，而项目中可能用得上的函数式接口：
 * <pre>
 * | Group         | FunctionalInterface  | method                           |
 * | ------------- | -------------------- | -------------------------------- |
 * | UnaryOperator | BoolUnaryOperator    | boolean applyAsBool (boolean)    |
 * | UnaryOperator | CharUnaryOperator    | char applyAsChar(char)           |
 * | Throwing      | Executable           | void execute() throws E          |
 * | Throwing      | ThrowingConsumer     | void accept(T) throws E          |
 * | Throwing      | ThrowingFunction     | R apply(T) throws E              |
 * | Throwing      | ThrowingPredicate    | boolean test(T) throws E         |
 * | Throwing      | ThrowingSupplier     | T get() throws E                 |
 * | Optional      | OptionalSupplier     | Optional&lt;T&gt; get() throws E       |
 * | Optional      | ToOptionalBiFunction | Optional&lt;R&gt; apply(T,U)           |
 * | Optional      | ToOptionalFunction   | Optional&lt;R&gt; apply(T)             |
