public HttpMessageWriterView(Encoder<?> encoder)
```
    Constructor with an Encoder.
  - HttpMessageWriterView
```
public HttpMessageWriterView(HttpMessageWriter<?> writer)
```
    Constructor with a fully initialized HttpMessageWriter.
- Method Detail
  - getMessageWriter
```
public HttpMessageWriter<?> getMessageWriter()
```
    Return the configured message writer.
  - getSupportedMediaTypes
```
public List<MediaType> getSupportedMediaTypes()
```
    Return the list of media types this View supports, or an empty list.
    The implementation of this method for HttpMessageWriterView delegates to HttpMessageWriter.getWritableMediaTypes().
    Specified by:
    getSupportedMediaTypes in interface View
  - setModelKeys
```
public void setModelKeys(@Nullable
                         Set<String> modelKeys)
```
    Set the attributes in the model that should be rendered by this view. When set, all other model attributes will be ignored. The matching attributes are further narrowed with HttpMessageWriter.canWrite(org.springframework.core.ResolvableType, org.springframework.http.MediaType). The matching attributes are processed as follows:
    0: nothing is written to the response body.
    1: the matching attribute is passed to the writer.
    2..N: if the writer supports Map, write all matches; otherwise raise an IllegalStateException.
  - getModelKeys
```
public final Set<String> getModelKeys()
```
    Return the configured model keys.
  - render
```
public reactor.core.publisher.Mono<Void> render(@Nullable
                                                Map<String,?> model,
                                                @Nullable
                                                MediaType contentType,
                                                ServerWebExchange exchange)
```
    Description copied from interface: View
    Render the view based on the given HandlerResult. Implementations can access and use the model or only a specific attribute in it.
    Specified by:
    render in interface View
    Parameters:
    model - a Map with name Strings as keys and corresponding model objects as values (Map can also be null in case of empty model)
    contentType - the content type selected to render with which should match one of the supported media types.
    exchange - the current exchange
    Returns:
    Mono to represent when and if rendering succeeds
