Class DmcHashedAttribute<E extends DmcMappedAttributeIF>

java.lang.Object

org.dmd.dmc.DmcAttribute<E>

org.dmd.dmc.DmcHashedAttribute<E>

All Implemented Interfaces:

Serializable, Cloneable, Comparable<String>

Direct Known Subclasses:

DmcTypeIntegerToBoolean, DmcTypeIntegerToString, DmcTypeIntegerToUUIDLite, DmcTypeStringToString

public abstract class DmcHashedAttribute<E extends DmcMappedAttributeIF>
extends DmcAttribute<E>
implements Serializable

The DmcHashedAttribute serves as the base for multi-valued attributes that can be stored and accessed via a Map, either a HashMap, or a TreeMap. This derivation merely ensures that the underlying values implement the DmcMappedAttributeIF interface.

Also, hashed attributes are inherently multi-valued. The set() mechanism is disabled and will throw an exception if you try to use it on a hashed attribute. You may only use the add() and del() functions on a hashed attribute.
