Class DBObjectIDMap<V>

java.lang.Object

oracle.javatools.db.util.DBObjectIDMap<V>

All Implemented Interfaces:

java.util.Map<DBObjectID,V>

public class DBObjectIDMap<V>
extends java.lang.Object

Map implementation to use when the key is a DBObjectID. Any API users that wish to key a Map using DBObjectIDs should use this implementation to be sure of proper comparison of the IDs when adding to the Map.

11.1.2.0.0

Constructor Detail

DBObjectIDMap

public DBObjectIDMap(boolean strict)

Constructs a new map whose DBObjectID keys will optionally be compared strictly.

This Map will not be thread safe, use DBObjectIDMap(boolean,boolean) if you require thread safety.

DBObjectID#equals(boolean)

DBObjectIDMap

public DBObjectIDMap(boolean strict,
                     boolean concurrent)

Constructs a new map that is optionally concurrent (i.e. thread safe). Choosing to make the map thread safe when it isn't required means the map will be slower than it needs to be. The DBObjectID keys will optionally be compared strictly.

Parameters:

strict - whether the keys will be compared strictly

concurrent - whether the map will be thread safe
