public final class FastInfosetStreamWriterOutput
extends XMLStreamWriterOutput

XmlOutput for StAXDocumentSerializer.

This class is responsible for managing the indexing of elements, attributes and local names that are known to JAXB by way of the JAXBContext (generated from JAXB beans or schema). The pre-encoded UTF-8 representations of known local names are also utilized.

The lookup of elements, attributes and local names with respect to a context is very efficient. It relies on an incrementing base line so that look up is performed in O(1) time and only uses static memory. When the base line reaches a point where integer overflow will occur the arrays and base line are reset (such an event is rare and will have little impact on performance).

A weak map of JAXB contexts to optimized tables for attributes, elements and local names is utilized and stored on the LowLevel StAX serializer. Thus, optimized serializing can work other multiple serializing of JAXB beans using the same LowLevel StAX serializer instance. This approach works best when JAXB contexts are only created once per schema or JAXB beans (which is the recommended practice as the creation JAXB contexts are expensive, they are thread safe and can be reused).

                          NamespaceContextImpl nsContext)
                   throws java.io.IOException,
                          org.xml.sax.SAXException,
                          javax.xml.stream.XMLStreamException

Description copied from class: XmlOutputAbstractImpl

Called at the very beginning.

Specified by:

startDocument in interface XmlOutput

Overrides:

startDocument in class XMLStreamWriterOutput

Parameters:

serializer - the XMLSerializer that coordinates this whole marshalling episode.

fragment - true if we are marshalling a fragment.

Throws:

java.io.IOException

org.xml.sax.SAXException

javax.xml.stream.XMLStreamException

endDocument

public void endDocument(boolean fragment)
                 throws java.io.IOException,
                        org.xml.sax.SAXException,
                        javax.xml.stream.XMLStreamException

Description copied from class: XmlOutputAbstractImpl

Called at the very end.

Specified by:

endDocument in interface XmlOutput

Overrides:

endDocument in class XMLStreamWriterOutput

Parameters:

fragment - false if we are writing the whole document.

Throws:

java.io.IOException

org.xml.sax.SAXException

javax.xml.stream.XMLStreamException

beginStartTag

public void beginStartTag(Name name)
                   throws java.io.IOException

Description copied from class: XmlOutputAbstractImpl

Writes a start tag.

At this point XmlOutputAbstractImpl.nsContext holds namespace declarations needed for this new element.

This method is used for writing tags that are indexed.

Specified by:

beginStartTag in interface XmlOutput

Overrides:

beginStartTag in class XmlOutputAbstractImpl

Throws:

java.io.IOException

beginStartTagWithNamespaces

public void beginStartTagWithNamespaces(Name name)
                                 throws java.io.IOException

Throws:

java.io.IOException

                      java.lang.String value)
               throws java.io.IOException

Specified by:

attribute in interface XmlOutput

Overrides:

attribute in class XmlOutputAbstractImpl

Throws:

java.io.IOException

endStartTag

public void endStartTag()
                 throws java.io.IOException

Specified by:

endStartTag in interface XmlOutput

Overrides:

endStartTag in class XMLStreamWriterOutput

Throws:

java.io.IOException

endTag
