Constructor Detail

SourceProvider.SourceWriter

public SourceProvider.SourceWriter(@Context
                                   Injectable<SAXParserFactory> spf,
                                   @Context
                                   Injectable<TransformerFactory> tf)
Method Detail

isWriteable

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

Specified by:
isWriteable in interface MessageBodyWriter<Source>
Parameters:
t - the class of object that is to be written.
gt - 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.
as - 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(Source o,
                    Class<?> type,
                    Type genericType,
                    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<Source>
Parameters:
o - 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(Source o,
                    Class<?> t,
                    Type gt,
                    Annotation[] as,
                    MediaType mediaType,
                    MultivaluedMap<String,Object> httpHeaders,
                    OutputStream entityStream)
             throws IOException
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<Source>
Parameters:
o - the instance to write.
t - the class of object that is to be written.
gt - 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.
as - 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:
IOException - if an IO error arises
