public class AttributeValuesMap
extends OdbHashMap<java.lang.String,java.lang.Object>

A Map to contain values of attributes of an object. It is used to optimize a criteria query execution where ODB , while reading an instance data, tries to retrieve only values of attributes involved in the query instead of reading the entire object.
