## Detailed Description

A mix-in to implement object unmarshalling.

## Member Function Documentation

## processAttribute()

virtual void xmltooling::AbstractXMLObjectUnmarshaller::processAttribute | ( | const xercesc::DOMAttr * | attribute | ) |

protected virtual

Called after an attribute has been unmarshalled so that it can be added to the XMLObject.

Parameters

  attribute | the attribute being unmarshalled

Exceptions

  UnmarshallingException | thrown if there is a problem adding the attribute to the XMLObject

## processChildElement()

virtual void xmltooling::AbstractXMLObjectUnmarshaller::processChildElement | ( | XMLObject * | child,
|  | const xercesc::DOMElement * | childRoot )

protected virtual

Called after a child element has been unmarshalled so that it can be added to the parent XMLObject.

Parameters

  child | pointer to the child XMLObject
  childRoot | root element of the child (must not be stored, just a hint)

Exceptions

  UnmarshallingException | thrown if there is a problem adding the child to the parent

## unmarshall()

XMLObject * xmltooling::AbstractXMLObjectUnmarshaller::unmarshall | ( | xercesc::DOMElement * | element,
|  | bool | bindDocument = false )

virtual

Unmarshalls the given W3C DOM element into the XMLObject.

The root of a given XML construct should be unmarshalled with the bindDocument parameter set to true.

Parameters

  element | the DOM element to unmarshall
  bindDocument | true iff the resulting XMLObject should take ownership of the DOM's Document

Returns
  the unmarshalled XMLObject

Exceptions

  UnmarshallingException | thrown if an error occurs unmarshalling the DOM element into the XMLObject

Implements xmltooling::XMLObject.

## unmarshallAttributes()

virtual void xmltooling::AbstractXMLObjectUnmarshaller::unmarshallAttributes | ( | const xercesc::DOMElement * | domElement | ) |

protected virtual

Unmarshalls the attributes from the given DOM Element into the XMLObject.

If the attribute is an XML namespace declaration the namespace is added via XMLObject::addNamespace(). If it is a schema type (xsi:type) the schema type is added via XMLObject::setSchemaType(). All other attributes are passed to the processAttribute hook.

Parameters

  domElement | the DOM Element whose attributes will be unmarshalled

Exceptions

  UnmarshallingException | thrown if there is a problem unmarshalling an attribute

## unmarshallContent()

virtual void xmltooling::AbstractXMLObjectUnmarshaller::unmarshallContent | ( | const xercesc::DOMElement * | domElement | ) |

protected virtual

Unmarshalls a given Element's child nodes.

The resulting XMLObject children and content are passed to processChildElement() or processText() for further processing.

Parameters

  domElement | the DOM Element whose children will be unmarshalled

Exceptions

  UnmarshallingException | thrown if an error occurs unmarshalling the child elements
