Specified by:

getPayloadNamespaceURI in class Message

Returns:

null if a Message doesn't have any payload.

hasPayload

public boolean hasPayload()

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

Writes the whole envelope as SAX events.

Overrides:

writeTo in class AbstractMessageImpl

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:

org.xml.sax.SAXException

copy

public Message copy()

Description copied from class: Message

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.

Specified by:

copy in class Message

writePayloadTo

protected void writePayloadTo(org.xml.sax.ContentHandler contentHandler,
                              org.xml.sax.ErrorHandler errorHandler,
                              boolean fragment)
                       throws org.xml.sax.SAXException

Description copied from class: AbstractMessageImpl

Writes the payload to SAX events.

Specified by:

writePayloadTo in class AbstractMessageImpl

fragment - 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:

org.xml.sax.SAXException

isOneWay

public boolean isOneWay(@NotNull
                        WSDLPort port)

Description copied from class: Message

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 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.

getAttachments

@NotNull
public AttachmentSet getAttachments()

Description copied from class: Message

Gets the attachments of this message (attachments live outside a message.)

Overrides:

getAttachments in class Message
