Method Detail

isReadable

public boolean isReadable(Class<?> type,
                          Type genericType,
                          Annotation[] annotations,
                          MediaType mediaType)
Description copied from interface: MessageBodyReader
Ascertain if the MessageBodyReader can produce an instance of a particular type. The type parameter gives the class of the object that should be produced, the genericType parameter gives the java.lang.reflect.Type of the object that should be produced. E.g. if the object to be produced is List, the type parameter will be java.util.List and the genericType parameter will be java.lang.reflect.ParameterizedType.

Parameters:
type - the class of object to be produced.
genericType - the type of object to be produced. E.g. if the message body is to be converted into a method parameter, this will be the formal type of the method parameter as returned by Method.getGenericParameterTypes.
annotations - an array of the annotations on the declaration of the artifact that will be initialized with the produced instance. E.g. if the message body is to be converted into a method parameter, this will be the annotations on that parameter returned by Method.getParameterAnnotations.
mediaType - the media type of the HTTP entity, if one is not specified in the request then application/octet-stream is used.
Returns:
true if the type is supported, otherwise false.

isWriteable

public boolean isWriteable(Class<?> type,
                           Type genericType,
                           Annotation[] annotations,
                           MediaType mediaType)
Description copied from interface: MessageBodyWriter
Ascertain if the MessageBodyWriter supports a particular type.

Parameters:
type - the class of object that is to be written.
genericType - the type of object 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 on the resource method that returns the object.
mediaType - the media type of the HTTP entity.
Returns:
true if the type is supported, otherwise false.

isSupported

protected boolean isSupported(MediaType m)
