public class DomMapperBase
extends DocumentModelMapperBase

Base implementation for custom marshaller/unmarshallers to DOM representation. This provides the basic code used for both single element and content list handling.

Constructor Detail

DomMapperBase

protected DomMapperBase()
                 throws JiBXException

Constructor. Initializes the document used by this marshaller/unmarshaller instance as the owner of all DOM components.

Throws:

JiBXException - on error creating document

Method Detail

marshalNode

protected void marshalNode(Node node)
                    throws JiBXException,
                           IOException

Marshal node.

Parameters:

node - node to be marshalled

Throws:

JiBXException - on error in marshalling

IOException - on error writing to output

marshalContent

protected void marshalContent(NodeList content)
                       throws JiBXException,
                              IOException

Marshal node list.

Parameters:

content - list of nodes to marshal

Throws:

JiBXException - on error in marshalling

IOException - on error writing to output

marshalElement

protected void marshalElement(Element element)
                       throws JiBXException,
                              IOException

Marshal element with all attributes and content.

Parameters:

element - element to be marshalled

Throws:

JiBXException - on error in marshalling

IOException - on error writing to output

unmarshalNode

protected Node unmarshalNode()
                      throws JiBXException,
                             IOException

Unmarshal single node. This unmarshals the next node from the input stream, up to the close tag of the containing element.

Returns:

unmarshalled node

Throws:

JiBXException - on error in unmarshalling

IOException - on error reading input

unmarshalContent

protected void unmarshalContent(Node parent)
                         throws JiBXException,
                                IOException

Unmarshal node content. This unmarshals everything up to the containing element close tag, adding each component to the content list supplied. On return, the parse position will always be at an END_TAG.

Parameters:

parent - node to which children are to be added

Throws:

JiBXException - on error in unmarshalling

IOException - on error reading input

unmarshalElement

protected Element unmarshalElement()
                            throws JiBXException,
                                   IOException

Unmarshal element with all attributes and content. This must be called with the unmarshalling context positioned at a START_TAG event.

Returns:

unmarshalled element

Throws:

JiBXException - on error in unmarshalling

IOException - on error reading input
