Class UniqueObject

java.lang.Object
  org.qtitools.qti.node.AbstractNode
      org.qtitools.qti.node.AbstractObject

All Implemented Interfaces:

java.io.Serializable, XmlNode, XmlObject, Validatable

Direct Known Subclasses:

AssessmentItem, ControlObject, VariableDeclaration

public abstract class UniqueObject
extends AbstractObject

Parent of all unique nodes. Unique node must have identifier attribute and this attribute must be used for identification of node and must be unique in whole xml tree.

For example variable expression is not unique node. It contains identifier attribute, but it is not used for identification of variable expression.

Use this class only if node is unique in whole xml tree.
