Examples of DatabaseRecord

oracle.toplink.essentials.sessions.DatabaseRecord
Purpose: Define a representation of a database row as field=>value pairs. This is the database row implementation class, the Record or java.util.Map interfaces should be used to access this class instead of the implemention class.
Responsibilities:
- Implement the common hashtable collection protocol.
- Allow get and put on the field or field name.
