Method Summary

All Methods Instance Methods Abstract Methods Default Methods
Modifier and Type	Method	Description
`boolean`	`canRead(ResolvableType elementType, MediaType mediaType)`	Whether the given object type is supported by this reader.
`List<MediaType>`	`getReadableMediaTypes()`	Return the `MediaType`'s that this reader supports.
`default reactor.core.publisher.Flux<T>`	`read(ResolvableType actualType, ResolvableType elementType, ServerHttpRequest request, ServerHttpResponse response, Map<String,Object> hints)`	Server-side only alternative to `read(ResolvableType, ReactiveHttpInputMessage, Map)` with additional context available.
`reactor.core.publisher.Flux<T>`	`read(ResolvableType elementType, ReactiveHttpInputMessage message, Map<String,Object> hints)`	Read from the input message and encode to a stream of objects.
`default reactor.core.publisher.Mono<T>`	`readMono(ResolvableType actualType, ResolvableType elementType, ServerHttpRequest request, ServerHttpResponse response, Map<String,Object> hints)`	Server-side only alternative to `readMono(ResolvableType, ReactiveHttpInputMessage, Map)` with additional, context available.
`reactor.core.publisher.Mono<T>`	`readMono(ResolvableType elementType, ReactiveHttpInputMessage message, Map<String,Object> hints)`	Read from the input message and encode to a single object.

- Method Detail
  - getReadableMediaTypes
```
List<MediaType> getReadableMediaTypes()
```
    Return the MediaType's that this reader supports.
  - canRead
```
boolean canRead(ResolvableType elementType,
                @Nullable
                MediaType mediaType)
```
    Whether the given object type is supported by this reader.
    Parameters:
    elementType - the type of object to check
    mediaType - the media type for the read (possibly null)
    Returns:
    true if readable, false otherwise
  - read
```
reactor.core.publisher.Flux<T> read(ResolvableType elementType,
                                    ReactiveHttpInputMessage message,
                                    Map<String,Object> hints)
```
    Read from the input message and encode to a stream of objects.
    Parameters:
    elementType - the type of objects in the stream which must have been previously checked via canRead(ResolvableType, MediaType)
    message - the message to read from
    hints - additional information about how to read and decode the input
    Returns:
    the decoded stream of elements
  - readMono
```
reactor.core.publisher.Mono<T> readMono(ResolvableType elementType,
                                        ReactiveHttpInputMessage message,
                                        Map<String,Object> hints)
```
    Read from the input message and encode to a single object.
    Parameters:
    elementType - the type of objects in the stream which must have been previously checked via canRead(ResolvableType, MediaType)
    message - the message to read from
    hints - additional information about how to read and decode the input
    Returns:
    the decoded object
  - read
```
default reactor.core.publisher.Flux<T> read(ResolvableType actualType,
                                            ResolvableType elementType,
                                            ServerHttpRequest request,
                                            ServerHttpResponse response,
                                            Map<String,Object> hints)
```
    Server-side only alternative to read(ResolvableType, ReactiveHttpInputMessage, Map) with additional context available.
    Parameters:
    actualType - the actual type of the target method parameter; for annotated controllers, the MethodParameter can be accessed via ResolvableType.getSource().
    elementType - the type of Objects in the output stream
    request - the current request
    response - the current response
    hints - additional information about how to read the body
    Returns:
    the decoded stream of elements
  - readMono
```
