oracle.javatools.db.util
Class DBObjectMap<K extends DBObject,V>

java.lang.Object
  oracle.javatools.db.util.DBObjectMap<K,V>

All Implemented Interfaces:

java.util.Map<K,V>

public class DBObjectMap<K extends DBObject,V>
extends java.lang.Object

Map implementation to use when the key is a DBObject. Any API users that wish to key a Map using DBObjects should use this implementation to be sure of proper comparison of the objects by name and type without causing the object to be "built" (e.g queried from the database) in order to perform an equality operation.

This Map implementation is not synchronized, use Collections.synchronizedMap if you require thread safety.

Since:

11.1.2.0.0
