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 instance that should be produced, the genericType parameter gives the java.lang.reflect.Type of the instance that should be produced. E.g. if the instance to be produced is List<String>, the type parameter will be java.util.List and the genericType parameter will be java.lang.reflect.ParameterizedType.

Parameters:

type -

genericType -

annotations -

mediaType - the media type of the HTTP entity, if one is not specified in the request then application/octet-stream is used.

Returns:

readFrom

public IIOImage readFrom(Class<IIOImage> type,
                         Type genericType,
                         Annotation[] annotations,
                         MediaType mediaType,
                         MultivaluedMap<String,String> httpHeaders,
                         InputStream entityStream)
                  throws IOException

Description copied from interface: MessageBodyReader

Read a type from the InputStream.

In case the entity input stream is empty, the reader is expected to either return a Java representation of a zero-length entity or throw a NoContentException in case no zero-length entity representation is defined for the supported Java type. A NoContentException, if thrown by a message body reader while reading a server request entity, is automatically translated by JAX-RS server runtime into a BadRequestException wrapping the original NoContentException and rethrown for a standard processing by the registered exception mappers.

Parameters:

type -

genericType -

annotations -

mediaType -

httpHeaders -

entityStream -

Returns:

Throws:

IOException

WebApplicationException

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 -

genericType -

annotations -

mediaType - the media type of the HTTP entity.

Returns:

writeTo

public void writeTo(IIOImage t,
                    Class<?> type,
                    Type genericType,
                    Annotation[] annotations,
                    MediaType mediaType,
                    MultivaluedMap<String,Object> httpHeaders,
                    OutputStream entityStream)
             throws IOException

Description copied from interface: MessageBodyWriter

Write a type to an HTTP message. The message header map is mutable but any changes must be made before writing to the output stream since the headers will be flushed prior to writing the message body.

Parameters:

t -

type -

genericType -

annotations -

mediaType -

httpHeaders -

entityStream -

Throws:

IOException

WebApplicationException
