## 4. - 函数式编程
|
|
|
|
### 4.1. PredicateTools
|
|
|
|
`PredicateTools` 用于 `Predicate` 的相关操作。
|
|
|
|
### 4.2. Functional interfaces
|
|
|
|
补充可能用得上的函数式接口：
|
|
|
|
| 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<T> get() throws E |
|
|
| Optional | **ToOptionalBiFunction** | Optional<R> apply(T,U) |
|
|
| Optional | **ToOptionalFunction** | Optional<R> apply(T) |
