All Methods Static Methods Instance Methods Abstract Methods Default Methods
Modifier and Type	Method	Description
`default ExchangeFilterFunction`	`andThen(ExchangeFilterFunction afterFilter)`	Return a composed filter function that first applies this filter, and then applies the given `"after"` filter.
`default ExchangeFunction`	`apply(ExchangeFunction exchange)`	Apply this filter to the given ExchangeFunction, resulting in a filtered exchange function.
`reactor.core.publisher.Mono<ClientResponse>`	`filter(ClientRequest request, ExchangeFunction next)`	Apply this filter to the given request and exchange function.
`static ExchangeFilterFunction`	`ofRequestProcessor(Function<ClientRequest,reactor.core.publisher.Mono<ClientRequest>> processor)`	Adapt the given request processor function to a filter function that only operates on the `ClientRequest`.
`static ExchangeFilterFunction`	`ofResponseProcessor(Function<ClientResponse,reactor.core.publisher.Mono<ClientResponse>> processor)`	Adapt the given response processor function to a filter function that only operates on the `ClientResponse`.

reactor.core.publisher.Mono<ClientResponse> filter(ClientRequest request,
                                                   ExchangeFunction next)
```
    Apply this filter to the given request and exchange function.
    The given ExchangeFunction represents the next entity in the chain, to be invoked via invoked in order to proceed with the exchange, or not invoked to shortcut the chain.
    Parameters:
    request - the current request
    next - the next exchange function in the chain
    Returns:
    the filtered response

```
default ExchangeFilterFunction andThen(ExchangeFilterFunction afterFilter)
```
    Return a composed filter function that first applies this filter, and then applies the given "after" filter.
    Parameters:
    afterFilter - the filter to apply after this filter
    Returns:
    the composed filter

```
    Apply this filter to the given ExchangeFunction, resulting in a filtered exchange function.
    Parameters:
    exchange - the exchange function to filter
    Returns:
    the filtered exchange function
  - ofRequestProcessor
```
static ExchangeFilterFunction ofRequestProcessor(Function<ClientRequest,reactor.core.publisher.Mono<ClientRequest>> processor)
```
    Adapt the given request processor function to a filter function that only operates on the ClientRequest.
    Parameters:
    processor - the request processor
    Returns:
    the resulting filter adapter
  - ofResponseProcessor
```
static ExchangeFilterFunction ofResponseProcessor(Function<ClientResponse,reactor.core.publisher.Mono<ClientResponse>> processor)
```
    Adapt the given response processor function to a filter function that only operates on the ClientResponse.
    Parameters:
    processor - the response processor
    Returns:
    the resulting filter adapter
