Constructor Detail

SAAJMessage

public SAAJMessage(javax.xml.soap.SOAPMessage sm)
Method Detail

hasHeaders

public boolean hasHeaders()
Description copied from class: Message
Returns true if headers are present in the message.

Specified by:
hasHeaders in class Message
Returns:
true if headers are present.

getHeaders

@NotNull
public HeaderList getHeaders()
Description copied from class: Message
Gets all the headers of this message.

Implementation Note

Message implementation is allowed to defer the construction of HeaderList object. So if you only want to check for the existence of any header element, use Message.hasHeaders().

Specified by:
getHeaders in class Message
Returns:
always return the same non-null object.

getAttachments

@NotNull
public AttachmentSet getAttachments()
Gets the attachments of this message (attachments live outside a message.)

Overrides:
getAttachments in class Message

hasAttachments

protected boolean hasAttachments()
Optimization hint for the derived class to check if we may have some attachments.

Overrides:
hasAttachments in class Message

getPayloadLocalPart

@Nullable
public String getPayloadLocalPart()
Description copied from class: Message
Gets the local name of the payload element.

Specified by:
getPayloadLocalPart in class Message
Returns:
null if a Message doesn't have any payload.

getPayloadNamespaceURI

public String getPayloadNamespaceURI()
Description copied from class: Message
Gets the namespace URI of the payload element.

Specified by:
getPayloadNamespaceURI in class Message
Returns:
null if a Message doesn't have any payload.

hasPayload

public boolean hasPayload()
Description copied from class: Message
Returns true if a Message has a payload.

A message without a payload is a SOAP message that looks like:


 <S:Envelope>
   <S:Header>
     ...
   </S:Header>
   <S:Body />
 </S:Envelope>
 

Specified by:
hasPayload in class Message

readEnvelopeAsSource

public Source readEnvelopeAsSource()
Description copied from class: Message
Consumes this message including the envelope. returns it as a Source object.

Specified by:
readEnvelopeAsSource in class Message

readAsSOAPMessage

public javax.xml.soap.SOAPMessage readAsSOAPMessage()
                                             throws javax.xml.soap.SOAPException
Description copied from class: Message
Creates the equivalent SOAPMessage from this message. This consumes the message.

Specified by:
readAsSOAPMessage in class Message
Throws:
javax.xml.soap.SOAPException - if there's any error while creating a SOAPMessage.

readPayloadAsSource

public Source readPayloadAsSource()
Description copied from class: Message
Returns the payload as a Source object. This consumes the message.

Specified by:
readPayloadAsSource in class Message
Returns:
if there's no payload, this method returns null.

readPayloadAsJAXB

public <T> T readPayloadAsJAXB(Unmarshaller unmarshaller)
                    throws JAXBException
Description copied from class: Message
Reads the payload as a JAXB object by using the given unmarshaller. This consumes the message.

Specified by:
readPayloadAsJAXB in class Message
Throws:
JAXBException - If JAXB reports an error during the processing.

readPayloadAsJAXB

public <T> T readPayloadAsJAXB(Bridge<T> bridge)
                    throws JAXBException
Description copied from class: Message
Reads the payload as a JAXB object according to the given Bridge. This consumes the message.

Specified by:
readPayloadAsJAXB in class Message
Returns:
null if there's no payload.
Throws:
JAXBException - If JAXB reports an error during the processing.

readPayload

public javax.xml.stream.XMLStreamReader readPayload()
                                             throws javax.xml.stream.XMLStreamException
Description copied from class: Message
Reads the payload as a XMLStreamReader This consumes the message. The caller is encouraged to call XMLStreamReaderFactory.recycle(XMLStreamReader) when finished using the instance.

Specified by:
readPayload in class Message
Returns:
If there's no payload, this method returns null. Otherwise always non-null valid XMLStreamReader that points to the payload tag name.
Throws:
javax.xml.stream.XMLStreamException

writePayloadTo

public void writePayloadTo(javax.xml.stream.XMLStreamWriter sw)
                    throws javax.xml.stream.XMLStreamException
Description copied from class: Message
Writes the payload to StAX. This method writes just the payload of the message to the writer. This consumes the message. The implementation will not write XMLStreamWriter.writeStartDocument() nor XMLStreamWriter.writeEndDocument()

If there's no payload, this method is no-op.

Specified by:
writePayloadTo in class Message
Throws:
javax.xml.stream.XMLStreamException - If the XMLStreamWriter reports an error, or some other errors happen during the processing.

writeTo

public void writeTo(javax.xml.stream.XMLStreamWriter writer)
             throws javax.xml.stream.XMLStreamException
Description copied from class: Message
Writes the whole SOAP message (but not attachments) to the given writer. This consumes the message.

Specified by:
writeTo in class Message
Throws:
javax.xml.stream.XMLStreamException - If the XMLStreamWriter reports an error, or some other errors happen during the processing.

writeTo

public void writeTo(ContentHandler contentHandler,
                    ErrorHandler errorHandler)
             throws SAXException
Description copied from class: Message
Writes the whole SOAP envelope as SAX events.

This consumes the message.

Specified by:
writeTo in class Message
Parameters:
contentHandler - must not be nulll.
errorHandler - must not be null. any error encountered during the SAX event production must be first reported to this error handler. Fatal errors can be then thrown as SAXParseException. SAXExceptions thrown from ErrorHandler should propagate directly through this method.
Throws:
SAXException

copy

public Message copy()
Creates a copy of a Message.

This method creates a new Message whose header/payload/attachments/properties are identical to this Message. Once created, the created Message and the original Message behaves independently --- adding header/ attachment to one Message doesn't affect another Message at all.

Design Rationale

Since a Message body is read-once, sometimes (such as when you do fail-over, or WS-RM) you need to create an idential copy of a Message.

The actual copy operation depends on the layout of the data in memory, hence it's best to be done by the Message implementation itself.

copy in class Message
