Class WriteResistantMap<K,V>

java.lang.Object
  ariba.util.core.ReadOnlyMap<K,V>
      ariba.util.core.WriteResistantMap<K,V>

Type Parameters:

K - Key class

V - Value class

public class WriteResistantMap<K,V>
extends ReadOnlyMap<K,V>

Similar to a ReadOnlyMap, but with a method getMap enabling the caller to get direct access to the underlying Map, which may then be modified. This "hole in the firewall" should be used only with extreme caution, and in circumstances where an optimized way of modifying the state is jusified.
