Constructor Details

ElementBeanInfoImpl

protected ElementBeanInfoImpl(JAXBContextImpl grammar)

The constructor for the sole instanceof JaxBeanInfo for handling user-created JAXBElement. Such JaxBeanInfo is used only for marshalling. This is a hack.

Method Details

getElementNamespaceURI

public String getElementNamespaceURI(JAXBElement e)

Description copied from class: JaxBeanInfo

Returns the namespace URI portion of the element name, if the bean that this class represents is mapped from/to an XML element.

Specified by:

getElementNamespaceURI in class JaxBeanInfo<JAXBElement>

getElementLocalName

public String getElementLocalName(JAXBElement e)

Description copied from class: JaxBeanInfo

Returns the local name portion of the element name, if the bean that this class represents is mapped from/to an XML element.

Specified by:

getElementLocalName in class JaxBeanInfo<JAXBElement>

getLoader

public Loader getLoader(JAXBContextImpl context,
 boolean typeSubstitutionCapable)

Description copied from class: JaxBeanInfo

Gets the Loader that will unmarshall the given object.

Specified by:

getLoader in class JaxBeanInfo<JAXBElement>

Parameters:

context - The JAXBContextImpl object that governs this object. This object is taken as a parameter so that doesn't have to store them on its own. When this method is invoked from within the unmarshaller, tihs parameter can be null (because the loader is constructed already.)

typeSubstitutionCapable - If true, the returned Loader is capable of recognizing @xsi:type (if necessary) and unmarshals a subtype. This allowes an optimization where this bean info is guaranteed not to have a type substitution. If false, the returned Loader doesn't look for @xsi:type.

Returns:

must return non-null valid object

createInstance

public JAXBElement createInstance(UnmarshallingContext context)
                           throws IllegalAccessException,
InvocationTargetException,
InstantiationException

Description copied from class: JaxBeanInfo

Creates a new instance of the bean.

This operation is only supported when JaxBeanInfo.isImmutable() is false.

Specified by:

createInstance in class JaxBeanInfo<JAXBElement>

Parameters:

context - Sometimes the created bean remembers the corresponding source location,

Throws:

IllegalAccessException

InvocationTargetException

InstantiationException

createInstanceFromValue

public JAXBElement createInstanceFromValue(Object o)
                                    throws IllegalAccessException,
InvocationTargetException,
InstantiationException

Throws:

IllegalAccessException

InvocationTargetException

InstantiationException

reset

public boolean reset(JAXBElement e,
 UnmarshallingContext context)

Description copied from class: JaxBeanInfo

Resets the object to the initial state, as if the object is created fresh.

This is used to reuse an existing object for unmarshalling.

Specified by:

reset in class JaxBeanInfo<JAXBElement>

context - used for reporting any errors.

Returns:

true if the object was successfuly resetted. False if the object is not resettable, in which case the object will be discarded and new one will be created.

If the object is resettable but failed by an error, it should be reported to the context, then return false. If the object is not resettable to begin with, do not report an error.

getId

public String getId(JAXBElement e,
 XMLSerializer target)

Description copied from class: JaxBeanInfo

Gets the ID value of the given bean, if it has an ID value. Otherwise return null.

Specified by:

getId in class JaxBeanInfo<JAXBElement>

serializeBody

public void serializeBody(JAXBElement element,
 XMLSerializer target)
                   throws SAXException,
IOException,
XMLStreamException

Description copied from class: JaxBeanInfo

Serializes child elements and texts into the specified target.

Specified by:

serializeBody in class JaxBeanInfo<JAXBElement>

Throws:

SAXException

IOException

XMLStreamException

serializeRoot

public void serializeRoot(JAXBElement e,
 XMLSerializer target)
                   throws SAXException,
IOException,
XMLStreamException

Description copied from class: JaxBeanInfo

Serializes the bean as the root element.

In the java-to-schema binding, an object might marshal in two different ways depending on whether it is used as the root of the graph or not. In the former case, an object could marshal as an element, whereas in the latter case, it marshals as a type.

This method is used to marshal the root of the object graph to allow this semantics to be implemented.

It is doubtful to me if it's a good idea for an object to marshal in two ways depending on the context.

For schema-to-java, this is equivalent to JaxBeanInfo.serializeBody(Object, XMLSerializer).

Specified by:

serializeRoot in class JaxBeanInfo<JAXBElement>

Throws:

SAXException

IOException

XMLStreamException

serializeAttributes

public void serializeAttributes(JAXBElement e,
 XMLSerializer target)

Description copied from class: JaxBeanInfo

Serializes attributes into the specified target.

Specified by:

serializeAttributes in class JaxBeanInfo<JAXBElement>

serializeURIs

public void serializeURIs(JAXBElement e,
 XMLSerializer target)

Description copied from class: JaxBeanInfo

Declares all the namespace URIs this object is using at its top-level scope into the specified target.

Specified by:

serializeURIs in class JaxBeanInfo<JAXBElement>

getTransducer

public Transducer<JAXBElement> getTransducer()

Description copied from class: JaxBeanInfo

If the bean's representation in XML is just a text, this method return a Transducer that lets you convert values between the text and the bean.

Specified by:

getTransducer in class JaxBeanInfo<JAXBElement>

wrapUp

public void wrapUp()

Description copied from class: JaxBeanInfo

Called at the end of the JAXBContext initialization phase to clean up any unnecessary references.

Overrides:

wrapUp in class JaxBeanInfo<JAXBElement>

link

public void link(JAXBContextImpl grammar)

Description copied from class: JaxBeanInfo

Called after all the s are created.

Overrides:

link in class JaxBeanInfo<JAXBElement>
