  • Method Details

    • hasHeaders

      public boolean hasHeaders()
      Returns true if headers are present in the message.
      Specified by:
      hasHeaders in class com.sun.xml.ws.api.message.Message
      Returns:
      true if headers are present.

    • getHeaders

      public com.sun.xml.ws.api.message.HeaderList getHeaders()
      Gets all the headers of this message.

      Implementation Note

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

      Specified by:
      getHeaders in class com.sun.xml.ws.api.message.Message
      Returns:
      always return the same non-null object.

    • getAttachments

      public com.sun.xml.ws.api.message.AttachmentSet getAttachments()
      Gets the attachments of this message (attachments live outside a message.)
      Overrides:
      getAttachments in class com.sun.xml.ws.api.message.Message

    • hasAttachments

      protected boolean hasAttachments()
      Optimization hint for the derived class to check if we may have some attachments.
      Overrides:
      hasAttachments in class com.sun.xml.ws.api.message.Message

    • isOneWay

      public boolean isOneWay(@NotNull com.sun.xml.ws.api.model.wsdl.WSDLPort port)
      Returns true if this message is a request message for a one way operation according to the given WSDL. False otherwise.

      This method is functionally equivalent as doing getOperation(port).getOperation().isOneWay() (with proper null check and all.) But this method can sometimes work faster than that (for example, on the client side when used with SEI.)

      Overrides:
      isOneWay in class com.sun.xml.ws.api.message.Message
      Parameters:
      port - Messages are always created under the context of one WSDLPort and they never go outside that context. Pass in that "governing" WSDLPort object here. We chose to receive this as a parameter instead of keeping WSDLPort in a message, just to save the storage.

      The implementation of this method involves caching the return value, so the behavior is undefined if multiple callers provide different WSDLPort objects, which is a bug of the caller.

    • getPayloadLocalPart

      public String getPayloadLocalPart()
      Gets the local name of the payload element.
      Specified by:
      getPayloadLocalPart in class com.sun.xml.ws.api.message.Message
      Returns:
      null if a Message doesn't have any payload.

    • isFault

      public boolean isFault()
      Returns true if this message is a fault.

      Just a convenience method built on getPayloadNamespaceURI() and getPayloadLocalPart().

      Overrides:
      isFault in class com.sun.xml.ws.api.message.Message

    • getPayloadNamespaceURI

      public String getPayloadNamespaceURI()
      Gets the namespace URI of the payload element.
      Specified by:
      getPayloadNamespaceURI in class com.sun.xml.ws.api.message.Message
      Returns:
      null if a Message doesn't have any payload.

    • hasPayload

      public boolean hasPayload()
      Returns true if a Message has a payload.

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

      
 <xmp>
 <S:Envelope>
   <S:Header>
     ...
   </S:Header>
   <S:Body />
 </S:Envelope>
 </xmp>
      Specified by:
      hasPayload in class com.sun.xml.ws.api.message.Message

    • readPayloadAsSource

      public Source readPayloadAsSource()
      Returns the payload as a Source object. This consumes the message.
      Specified by:
      readPayloadAsSource in class com.sun.xml.ws.api.message.Message
      Returns:
      if there's no payload, this method returns null.

    • readAsSOAPMessage

      public javax.xml.soap.SOAPMessage readAsSOAPMessage() throws javax.xml.soap.SOAPException
      Creates the equivalent SOAPMessage from this message. This consumes the message.
      Specified by:
      readAsSOAPMessage in class com.sun.xml.ws.api.message.Message
      Throws:
      javax.xml.soap.SOAPException - if there's any error while creating a SOAPMessage.

      Specified by:
      readPayload in class com.sun.xml.ws.api.message.Message

      If there's no payload, this method returns null. Otherwise always non-null valid XMLStreamReader that points to the payload tag name.
      Throws:
      XMLStreamException

    • writePayloadTo

      public void writePayloadTo(XMLStreamWriter sw) throws XMLStreamException
      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 com.sun.xml.ws.api.message.Message
      Throws:
      XMLStreamException - If the XMLStreamWriter reports an error, or some other errors happen during the processing.

    • writeTo

      public void writeTo(XMLStreamWriter sw) throws XMLStreamException
      Writes the whole SOAP message (but not attachments) to the given writer. This consumes the message.
      Specified by:
      writeTo in class com.sun.xml.ws.api.message.Message
      Throws:
      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
      Writes the whole SOAP envelope as SAX events.

      This consumes the message.

      Specified by:
      writeTo in class com.sun.xml.ws.api.message.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 MessageWrapper 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.

      This method does NOT consume a message.

      To enable efficient copy operations, there's a few restrictions on how copied message can be used.

      1. The original and the copy may not be used concurrently by two threads (this allows two Messages to share some internal resources, such as JAXB marshallers.) Note that it's OK for the original and the copy to be processed by two threads, as long as they are not concurrent.
      2. The copy has the same 'life scope' as the original (this allows shallower copy, such as JAXB beans wrapped in JAXBMessage.)

      A 'life scope' of a message created during a message processing in a pipeline is until a pipeline processes the next message. A message cannot be kept beyond its life scope. (This experimental design is to allow message objects to be reused --- feedback appreciated.)

      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.

      The restrictions placed on the use of copied Message can be relaxed if necessary, but it will make the copy method more expensive.
