      org.activemath.omdocjdom.OJReferenceAttribute

All Implemented Interfaces:

Serializable, Cloneable

public class OJReferenceAttribute
extends org.jdom.Attribute

An attribute meant to contain a pointer value. Such objects contain the necessary tools to take advantage of the ID class from within an attribute. It is used in such attributes as <ref xref= or item for=.

Constructor Summary

OJReferenceAttribute(String attName, ID pointer)
This constructor creates an attribute within the OJConstants.OMDOC_NAMESPACE.

OJReferenceAttribute(String attName, ID pointer, org.jdom.Namespace ns)
This constructor keeps the value null computing it only when requested.

OJReferenceAttribute(String attName, String pointerString, org.jdom.Namespace namespace)
This constructor sets the value and builds the ID only if necessary.

Method Summary

protected void	computeID() Computes the ID object supposing it is given by the Attribute.value.
protected void	computeValue() Computes the value supposing pointerID is not null using ID.expressShortestRef(org.activemath.omdocjdom.OJElement, org.activemath.omdocjdom.OJElement).
