Method Detail

getStaticContentType

public ContentType getStaticContentType(Packet packet)

Return the soap 1.1 and soap 1.2 specific XOP packaged ContentType

Specified by:

getStaticContentType in interface Codec

Returns:

A non-null content type for soap11 or soap 1.2 content type

getStaticContentTypeStatic

public static ContentType getStaticContentTypeStatic(Packet packet,
                                                     SOAPVersion version)

encode

public ContentType encode(Packet packet,
                          OutputStream out)
                   throws IOException

Description copied from interface: Codec

Encodes an XML infoset portion of the Message (from <soap:Envelope> to </soap:Envelope>).

Internally, this method is most likely invoke Message.writeTo(XMLStreamWriter) to turn the message into infoset.

Specified by:

encode in interface Codec

out - Must not be null. The caller is responsible for closing the stream, not the callee.

Returns:

The MIME content type of the encoded message (such as "application/xml"). This information is often ncessary by transport.

Throws:

IOException - if a OutputStream throws IOException.

getSOAPXopContentType

public static String getSOAPXopContentType(String encoding,
                                           SOAPVersion version,
                                           String actionParameter)

getActionParameter

public static String getActionParameter(Packet packet,
                                        SOAPVersion version)

writeMimeHeaders

public static void writeMimeHeaders(String contentType,
                                    String contentId,
                                    OutputStream out)
                             throws IOException

Throws:

IOException

encode

public ContentType encode(Packet packet,
                          WritableByteChannel buffer)

Description copied from interface: Codec

The version of Codec.encode(Packet,OutputStream) that writes to NIO ByteBuffer.

TODO: for the convenience of implementation, write an adapter that wraps WritableByteChannel to OutputStream.

copy

public MtomCodec copy()

Description copied from interface: Codec

Creates a copy of this Codec.

Since Codec instance is not re-entrant, the caller who needs to encode two Messages simultaneously will want to have two Codec instances. That's what this method produces.

Implentation Note

Note that this method might be invoked by one thread while another thread is executing one of the Codec.encode(com.sun.xml.ws.api.message.Packet, java.io.OutputStream) methods. This should be OK because you'll be only copying things that are thread-safe, and creating new ones for thread-unsafe resources, but please let us know if this contract is difficult.

Specified by:

copy in interface Codec

Returns:

always non-null valid Codec that performs the encoding work in the same way --- that is, if you copy an FI codec, you'll get another FI codec.

Once copied, two Codecs may be invoked from two threads concurrently; therefore, they must not share any state that requires isolation (such as temporary buffer.)

If the Codec implementation is already re-entrant and multi-thread safe to begin with, then this method may simply return this.

decode

protected void decode(MimeMultipartParser mpp,
                      Packet packet)
               throws IOException

Parses a Packet from a MimeMultipartParser.

Throws:

IOException

determinePacketEncoding

public static String determinePacketEncoding(Packet packet)

getMimeType

public String getMimeType()

Description copied from interface: Codec

Get the MIME type associated with this Codec.

If available the MIME type will represent the media that the codec encodes and decodes. The MIME type returned will be the most general representation independent of an instance of this MIME type utilized as a MIME content-type.

Specified by:

getMimeType in interface Codec

Returns:

null if the MIME type can't be determined by the Codec implementation. Otherwise the MIME type is returned.

getMimeRootCodec

protected Codec getMimeRootCodec(Packet packet)

decode

public void decode(InputStream in,
                   String contentType,
                   Packet packet)
            throws IOException

Description copied from interface: Codec

Reads bytes from InputStream and constructs a Message.

The design encourages lazy decoding of a Message, where a Message is returned even before the whole message is parsed, and additional parsing is done as the Message body is read along. A Codec is most likely have its own implementation of Message for this purpose.

Specified by:

decode in interface Codec

Parameters:

in - the data to be read into a Message. The transport would have read any transport-specific header before it passes an InputStream, and InputStream is expected to be read until EOS. Never null.

Some transports, such as SMTP, may 'encode' data into another format (such as uuencode, base64, etc.) It is the caller's responsibility to 'decode' these transport-level encoding before it passes data into Codec.

contentType - The MIME content type (like "application/xml") of this byte stream. Thie text includes all the sub-headers of the content-type header. Therefore, in more complex case, this could be something like multipart/related; boundary="--=_outer_boundary"; type="multipart/alternative". This parameter must not be null.

packet - The parsed Message will be set to this Packet. Codec may add additional properties to this Packet. On a successful method completion, a Packet must contain a Message.

Throws:

IOException - if InputStream throws an exception.

decode

public void decode(ReadableByteChannel in,
                   String contentType,
                   Packet packet)

Specified by:

decode in interface Codec

writeln

public static void writeln(String s,
                           OutputStream out)
