Method Details

init

public void init(JAXBContextImpl context,
 ClassBeanInfoImpl beanInfo,
 Accessor<?,Map<QName,String>> attWildcard)

Completes the initialization.

To fix the cyclic reference issue, the main part of the initialization needs to be done after a is set to ClassBeanInfoImpl.loader.

startElement

public void startElement(UnmarshallingContext.State state,
 TagName ea)
                  throws SAXException

Description copied from class: Loader

Called when the loader is activated, which is when a new start tag is seen and when the parent designated this loader as the child loader.

The callee may change state.loader to designate another for the processing. It's the responsibility of the callee to forward the startElement event in such a case.

Overrides:

startElement in class Loader

ea - info about the start tag. never null.

Throws:

SAXException

childElement

public void childElement(UnmarshallingContext.State state,
 TagName arg)
                  throws SAXException

Description copied from class: Loader

Called when this loaderis an active loaderand we see a new child start tag.

The callee is expected to designate another loaderas a loaderthat processes this element, then it should also register a Receiver. The designated loaderwill become an active loader.

The default implementation reports an error saying an element is unexpected.

Overrides:

childElement in class Loader

Throws:

SAXException

getExpectedChildElements

public Collection<QName> getExpectedChildElements()

Description copied from class: Loader

Returns a set of tag names expected as possible child elements in this context.

Overrides:

getExpectedChildElements in class Loader

getExpectedAttributes

public Collection<QName> getExpectedAttributes()

Description copied from class: Loader

Returns a set of tag names expected as possible child elements in this context.

Overrides:

getExpectedAttributes in class Loader

text

public void text(UnmarshallingContext.State state,
 CharSequence text)
          throws SAXException

Description copied from class: Loader

Called when this loaderis an active loaderand we see a chunk of text. The runtime makes sure that adjacent characters (even those separated by comments, PIs, etc) are reported as one event. IOW, you won't see two text event calls in a row.

Overrides:

text in class Loader

Throws:

SAXException

leaveElement

public void leaveElement(UnmarshallingContext.State state,
 TagName ea)
                  throws SAXException

Description copied from class: Loader

Called when this loaderis an active loaderand we see an end tag.

Overrides:

leaveElement in class Loader

Throws:

SAXException

getBeanInfo

public JaxBeanInfo getBeanInfo()
