isReadable

public boolean isReadable(java.lang.Class<?> type,
                          java.lang.reflect.Type genericType,
                          java.lang.annotation.Annotation[] annotations,
                          MediaType mediaType)
Description copied from interface: MessageBodyReader
Ascertain if the MessageBodyReader can produce an instance of a particular type.

Specified by:
isReadable in interface MessageBodyReader<java.lang.Object>
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 Class.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 Class.getParameterAnnotations.
mediaType - the media type of the HTTP entity.
Returns:
true if the type is supported, otherwise false.

isWrapped

protected boolean isWrapped(java.lang.Class<?> type,
                            java.lang.reflect.Type genericType,
                            java.lang.annotation.Annotation[] annotations,

getJAXBObject

public java.lang.Object getJAXBObject(JAXBContextFinder finder,
                                      MediaType mediaType,
                                      java.lang.Class<?> clazz,
                                      org.w3c.dom.Element element)
                               throws javax.xml.bind.JAXBException
Throws:
javax.xml.bind.JAXBException

readFrom

public java.lang.Object readFrom(java.lang.Class<java.lang.Object> type,
                                 java.lang.reflect.Type genericType,
                                 java.lang.annotation.Annotation[] annotations,
                                 MediaType mediaType,
                                 MultivaluedMap<java.lang.String,java.lang.String> httpHeaders,
                                 java.io.InputStream entityStream)
                          throws java.io.IOException,
                                 WebApplicationException
Description copied from interface: MessageBodyReader
Read a type from the InputStream.

Specified by:
readFrom in interface MessageBodyReader<java.lang.Object>
Parameters:
type - the type that is to be read from the entity stream.
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 Class.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 Class.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:
java.io.IOException - if an IO error arises
WebApplicationException - if a specific HTTP error response needs to be produced. Only effective if thrown prior to the response being committed.

isWriteable

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

Specified by:
isWriteable in interface MessageBodyWriter<java.lang.Object>
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.

getSize

public long getSize(java.lang.Object entry,
                    java.lang.Class<?> type,
                    java.lang.reflect.Type genericType,
                    java.lang.annotation.Annotation[] annotations,
                    MediaType mediaType)
Description copied from interface: MessageBodyWriter
Called before writeTo to ascertain the length in bytes of the serialized form of t. A non-negative return value is used in a HTTP Content-Length header.

Specified by:
getSize in interface MessageBodyWriter<java.lang.Object>
Parameters:
entry - the instance to write
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 by 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:
length in bytes or -1 if the length cannot be determined in advance

writeTo

public void writeTo(java.lang.Object target,
                    java.lang.Class<?> type,
                    java.lang.reflect.Type genericType,
                    java.lang.annotation.Annotation[] annotations,
                    MediaType mediaType,
                    MultivaluedMap<java.lang.String,java.lang.Object> httpHeaders,
                    java.io.OutputStream entityStream)
             throws java.io.IOException,
                    WebApplicationException
Description copied from interface: MessageBodyWriter
Write a type to an HTTP response. The response 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 response body.

Specified by:
writeTo in interface MessageBodyWriter<java.lang.Object>
Parameters:
target - the instance to write.
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 by 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.
httpHeaders - a mutable map of the HTTP response headers.
entityStream - the OutputStream for the HTTP entity. The implementation should not close the output stream.
Throws:
java.io.IOException - if an IO error arises
WebApplicationException - if a specific HTTP error response needs to be produced. Only effective if thrown prior to the response being committed.
