Class AttributeValuesPDPIter

java.lang.Object
  org.eclipse.higgins.util.idas.cp.AttributeValuesPDPIter

All Implemented Interfaces:

Iterator

public class AttributeValuesPDPIter

extends Object

implements Iterator

Helper function for policy based Higgins Context providers. This implementation allows for policy at critical points. After creation this object always transforms results as the accessor functions are called. The direction of the mapping is based on if object was created with provider or consumer values. You cannot use the object to access values untransformed!
