`default HandlerFilterFunction<T,R>`	`andThen(HandlerFilterFunction<T,T> after)`	Return a composed filter function that first applies this filter, and then applies the `after` filter.
`default HandlerFunction<R>`	`apply(HandlerFunction<T> handler)`	Apply this filter to the given handler function, resulting in a filtered handler function.
`reactor.core.publisher.Mono<R>`	`filter(ServerRequest request, HandlerFunction<T> next)`	Apply this filter to the given handler function.
`static HandlerFilterFunction<?,?>`	`ofRequestProcessor(Function<ServerRequest,reactor.core.publisher.Mono<ServerRequest>> requestProcessor)`	Adapt the given request processor function to a filter function that only operates on the `ServerRequest`.
`static <T extends ServerResponse,R extends ServerResponse> HandlerFilterFunction<T,R>`	`ofResponseProcessor(Function<T,reactor.core.publisher.Mono<R>> responseProcessor)`	Adapt the given response processor function to a filter function that only operates on the `ServerResponse`.

  - filter
```
reactor.core.publisher.Mono<R> filter(ServerRequest request,
                                      HandlerFunction<T> next)
```
    Apply this filter to the given handler function. The given handler function represents the next entity in the chain, and can be invoked in order to proceed to this entity, or not invoked to block the chain.
    参数:
    request - the request
    next - the next handler or filter function in the chain
    返回:
    the filtered response

  - andThen
```
default HandlerFilterFunction<T,R> andThen(HandlerFilterFunction<T,T> after)
```
    Return a composed filter function that first applies this filter, and then applies the after filter.
    参数:
    after - the filter to apply after this filter is applied
    返回:
    a composed filter that first applies this function and then applies the after function
  - apply
```
default HandlerFunction<R> apply(HandlerFunction<T> handler)
```
    Apply this filter to the given handler function, resulting in a filtered handler function.
    参数:
    handler - the handler function to filter
    返回:
    the filtered handler function
  - ofRequestProcessor
```
static HandlerFilterFunction<?,?> ofRequestProcessor(Function<ServerRequest,reactor.core.publisher.Mono<ServerRequest>> requestProcessor)
```
    Adapt the given request processor function to a filter function that only operates on the ServerRequest.
    参数:
    requestProcessor - the request processor
    返回:
    the filter adaptation of the request processor
  - ofResponseProcessor
```
static <T extends ServerResponse,R extends ServerResponse> HandlerFilterFunction<T,R> ofResponseProcessor(Function<T,reactor.core.publisher.Mono<R>> responseProcessor)
```
    Adapt the given response processor function to a filter function that only operates on the ServerResponse.
    参数:
    responseProcessor - the response processor
    返回:
    the filter adaptation of the request processor
