public final class WriterModel extends AbstractEntityProviderModel<MessageBodyWriter> {
Create new writer model instance. NOTE: This constructor is package-private on purpose.
Params:
  • provider – modelled message body writer instance.
  • types – supported media types as declared in @Consumes annotation attached to the provider class.
  • custom – custom flag.

public WriterModel(MessageBodyWriter provider, List<MediaType> types, Boolean custom) { super(provider, types, custom, MessageBodyWriter.class); }
Safely invokes isWriteable method on the underlying provider. Any exceptions will be logged at finer level.
Params:
  • type – the class of instance that is to be written.
  • genericType – the type of instance to be written, obtained either by reflection of a resource method return type or via inspection of the returned instance. GenericEntity provides a way to specify this information at runtime.
  • annotations – an array of the annotations attached to the message entity instance.
  • mediaType – the media type of the HTTP entity.
Returns:true if the type is supported, otherwise false.
