Class JAXBDispatchMessage
Message backed by a JAXB bean; this implementation is used when client uses
Dispatch mechanism in JAXB/MESSAGE mode; difference from JAXBMessage is
that jaxbObject holds whole SOAP message including SOAP envelope;
it's the client who is responsible for preparing message content.- Author:

Method Details

writePayloadTo
protected void writePayloadTo(ContentHandler contentHandler, ErrorHandler errorHandler, boolean fragment) throws SAXException Description copied from class:AbstractMessageImplWrites the payload to SAX events.- Specified by:
writePayloadToin classAbstractMessageImplfragment- if true, this method will fire SAX events without start/endDocument events, suitable for embedding this into a bigger SAX event sequence. if false, this method generaets a completely SAX event sequence on its own.- Throws:
SAXException
-
hasHeaders
public boolean hasHeaders()Description copied from class:MessageReturns true if headers are present in the message.- Specified by:
hasHeadersin classMessage- Returns:
- true if headers are present.
-
getHeaders
Description copied from class:MessageGets all the headers of this message.Implementation Note
Messageimplementation is allowed to defer the construction ofMessageHeadersobject. So if you only want to check for the existence of any header element, useMessage.hasHeaders().- Specified by:
getHeadersin classMessage- Returns:
- always return the same non-null object.
-
getPayloadLocalPart
Description copied from class:MessageGets the local name of the payload element.- Specified by:
getPayloadLocalPartin classMessage- Returns:
- null if a
Messagedoesn't have any payload.
-
getPayloadNamespaceURI
Description copied from class:MessageGets the namespace URI of the payload element.- Specified by:
getPayloadNamespaceURIin classMessage- Returns:
- null if a
Messagedoesn't have any payload.
-
hasPayload
public boolean hasPayload()Description copied from class:MessageReturns true if aMessagehas 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:
hasPayloadin classMessage
-
readPayloadAsSource
Description copied from class:MessageReturns the payload as aSourceobject. This consumes the message.- Specified by:
readPayloadAsSourcein classMessage- Returns:
- if there's no payload, this method returns null.
-
readPayload
Description copied from class:MessageReads the payload as aXMLStreamReaderThis consumes the message. The caller is encouraged to callXMLStreamReaderFactory.recycle(XMLStreamReader)when finished using the instance.- Specified by:
readPayloadin classMessage- Returns:
- If there's no payload, this method returns null.
Otherwise always non-null valid
XMLStreamReaderthat points to the payload tag name. - Throws:
XMLStreamException
-
writePayloadTo
Description copied from class:MessageWrites the payload to StAX. This method writes just the payload of the message to the writer. This consumes the message. The implementation will not writeXMLStreamWriter.writeStartDocument()norXMLStreamWriter.writeEndDocument()If there's no payload, this method is no-op.
- Specified by:
writePayloadToin classMessage- Throws:
XMLStreamException- If theXMLStreamWriterreports an error, or some other errors happen during the processing.
-
copy
Description copied from class:MessageCreates a copy of aMessage.This method creates a new
Messagewhose header/payload/attachments/properties are identical to thisMessage. Once created, the createdMessageand the originalMessagebehaves independently --- adding header/ attachment to oneMessagedoesn't affect anotherMessageat 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.
- 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. - 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
Messagebody is read-once, sometimes (such as when you do fail-over, or WS-RM) you need to create an identical copy of aMessage.The actual copy operation depends on the layout of the data in memory, hence it's best to be done by the
Messageimplementation itself.The restrictions placed on the use of copied
Messagecan be relaxed if necessary, but it will make the copy method more expensive.IMPORTANT
WHEN YOU IMPLEMENT OR CHANGE A
#copy()METHOD, YOU MUST USE THEMessage.copyFrom(com.sun.xml.ws.api.message.Message)METHOD IN THE IMPLEMENTATION. - The original and the copy may not be
used concurrently by two threads (this allows two
-
writeTo
Description copied from class:AbstractMessageImplDefault implementation that relies onMessage.writePayloadTo(XMLStreamWriter)- Overrides:
writeToin classAbstractMessageImpl- Throws:
XMLStreamException- If theXMLStreamWriterreports an error, or some other errors happen during the processing.
