public class RSocketPayloadReturnValueHandler
extends AbstractEncoderMethodReturnValueHandler
```
Extension of AbstractEncoderMethodReturnValueHandler that handles encoded content by wrapping data buffers as RSocket payloads and by passing those to the MonoProcessor from the RESPONSE_HEADER header.

Modifier and Type	Method	Description
`protected reactor.core.publisher.Mono<Void>`	`handleEncodedContent(reactor.core.publisher.Flux<DataBuffer> encodedContent, MethodParameter returnType, Message<?> message)`	Subclasses implement this method to handle encoded values in some way such as creating and sending messages.
`protected reactor.core.publisher.Mono<Void>`	`handleNoContent(MethodParameter returnType, Message<?> message)`	Invoked for a `null` return value, which could mean a void method or method returning an async type parameterized by void.

    Description copied from class: AbstractEncoderMethodReturnValueHandler
    Subclasses implement this method to handle encoded values in some way such as creating and sending messages.
    Specified by:
    handleEncodedContent in class AbstractEncoderMethodReturnValueHandler
    Parameters:
    encodedContent - the encoded content; each DataBuffer represents the fully-aggregated, encoded content for one value (i.e. payload) returned from the HandlerMethod.
    returnType - return type of the handler method that produced the data
    message - the input message handled by the handler method
    Returns:
    completion Mono<Void> for the handling
  - handleNoContent
```
protected reactor.core.publisher.Mono<Void> handleNoContent(MethodParameter returnType,
                                                            Message<?> message)
```
    Description copied from class: AbstractEncoderMethodReturnValueHandler
    Invoked for a null return value, which could mean a void method or method returning an async type parameterized by void.
    Specified by:
    handleNoContent in class AbstractEncoderMethodReturnValueHandler
    Parameters:
    returnType - return type of the handler method that produced the data
    message - the input message handled by the handler method
    Returns:
    completion Mono<Void> for the handling
