public class DomElementMapper
extends DomMapperBase
implements IMarshaller, IUnmarshaller, IAliasable
Custom element marshaller/unmarshaller to DOM representation. This allows
you to mix data binding and document model representations for XML within the
same application. You simply use this marshaller/unmarshaller with a linked
object of type org.w3c.dom.Element
(the actual runtime type -
the declared type is ignored and can be anything). If a name is supplied on a
reference that element name will always be matched when unmarshalling but
will be ignored when marshalling (with the actual DOM element name used). If
a namespace is supplied but no name, any element which does not use
that namespace will be unmarshalled. Finally, if no name is supplied this
will unmarshal a single element with any name.

DomElementMapper
Default constructor.- Throws:

- on error creating document
-
DomElementMapper
Aliased constructor. This takes a name definition for the element. It'll be used by JiBX when a name is supplied by the mapping which references this custom marshaller/unmarshaller.- Parameters:
uri
- namespace URI for the top-level elementindex
- namespace index corresponding to the defined URI within the marshalling context definitionsname
- local name for the top-level element- Throws:
JiBXException
- on error creating document

Method Details

isExtension
Description copied from interface:IMarshaller
Check if marshaller represents an extension mapping. This is used by the framework in generated code to verify compatibility of objects being marshalled using an abstract mapping.- Specified by:
isExtension
in interfaceIMarshaller
- Parameters:
mapname
- marshaller mapping name (generally the class name to be handled, or abstract mapping type name)- Returns:
true
if this mapping is an extension of the abstract mapping,false
if not
-
marshal
Description copied from interface:IMarshaller
Marshal instance of handled class. This method call is responsible for all handling of the marshalling of an object to XML text. It is called at the point where the start tag for the associated element should be generated.- Specified by:
marshal
in interfaceIMarshaller
- Parameters:
obj
- object to be marshalled (may benull
if property is not optional)ictx
- XML text output context- Throws:
JiBXException
- on error in marshalling process
-
isPresent
Description copied from interface:IUnmarshaller
Check if instance present in XML. This method can be called when the unmarshalling context is positioned at or just before the start of the data corresponding to an instance of this mapping. It verifies that the expected data is present.- Specified by:
isPresent
in interfaceIUnmarshaller
- Parameters:
ictx
- unmarshalling context- Returns:
true
if expected parse data found,false
if not- Throws:
JiBXException
- on error in unmarshalling process
-
unmarshal
Description copied from interface:IUnmarshaller
Unmarshal instance of handled class. This method call is responsible for all handling of the unmarshalling of an object from XML text, including creating the instance of the handled class if an instance is not supplied. When it is called the unmarshalling context is always positioned at or just before the start tag corresponding to the start of the class data.- Specified by:
unmarshal
in interfaceIUnmarshaller
- Parameters:
obj
- object to be unmarshalled (may benull
)ictx
- unmarshalling context- Returns:
- unmarshalled object (may be
null
) - Throws:
JiBXException
- on error in unmarshalling process
