Examples of com.sun.xml.stream.buffer.MutableXMLStreamBuffer

com.sun.xml.stream.buffer.MutableXMLStreamBuffer
A mutable stream-based buffer of an XML infoset.
A MutableXMLStreamBuffer is created using specific SAX and StAX-based creators. Utility methods on MutableXMLStreamBuffer are provided for such functionality that utilize SAX and StAX-based creators.
Once instantiated the same instance of a MutableXMLStreamBuffer may be reused for creation to reduce the amount of Objects instantiated and garbage collected that are required for internally representing an XML infoset.
A MutableXMLStreamBuffer is not designed to be created and processed concurrently. If done so unspecified behaviour may occur.

        // If we have swaRef, then that means we might have attachments.
        // to comply with the packet API, we need to eagerly turn the JAXB object into infoset
        // to correctly find out about attachments.


        try {
            MutableXMLStreamBuffer xsb = new MutableXMLStreamBuffer();


            Marshaller m = context.createMarshaller();
            AttachmentMarshallerImpl am = new AttachmentMarshallerImpl(attachments);
            m.setAttachmentMarshaller(am);
            am.cleanup();
            m.marshal(jaxbObject,xsb.createFromXMLStreamWriter());


            // any way to reuse this XMLStreamBuffer in StreamMessage?
            return new StreamMessage(headers,attachments,xsb.readAsXMLStreamReader(),soapVersion);
        } catch (JAXBException e) {
            throw new WebServiceException(e);
        } catch (XMLStreamException e) {
            throw new WebServiceException(e);
