Method Detail

isReadable

public boolean isReadable(Class<?> t,
                          Type gt,
                          Annotation[] as,
                          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.

Specified by:
isReadable in interface MessageBodyReader<StreamSource>
Parameters:
t - the class of object to be produced.
gt - 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.
as - 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.

readFrom

public StreamSource readFrom(Class<StreamSource> t,
                             Type gt,
                             Annotation[] as,
                             MediaType mediaType,
                             MultivaluedMap<String,String> httpHeaders,
                             InputStream entityStream)
                      throws IOException
Description copied from interface: MessageBodyReader
Read a type from the InputStream.

Specified by:
readFrom in interface MessageBodyReader<StreamSource>
Parameters:
t - the type that is to be read from the entity stream.
gt - 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.
as - 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.
httpHeaders - the read-only HTTP headers associated with HTTP entity.
entityStream - the InputStream of the HTTP entity. The caller is responsible for ensuring that the input stream ends when the entity has been consumed. The implementation should not close the input stream.
Returns:
the type that was read from the stream.
Throws:
IOException - if an IO error arises
