Class IdHashMap<V>

java.lang.Object

java.util.AbstractMap<Id,V>

java.util.HashMap<Id,V>

java.util.LinkedHashMap<Id,V>

net.okapia.osid.torrefacto.collect.IdHashMap<V>

Type Parameters:

V - the value type

All Implemented Interfaces:

Serializable, Cloneable, Map<Id,V>, SequencedMap<Id,V>

public class IdHashMap<V>
extends LinkedHashMap<Id,V>

A LinkedHashMap whose keys are hardened to org.osid.id.Id. It adds no behavior beyond fixing the key type; all map operations are inherited.

IdHashMap

public IdHashMap(int initialCapacity)

Constructs an empty HashMap with the specified initial capacity and the default load factor (0.75).

Parameters:

initialCapacity - the initial capacity.

Throws:

IllegalArgumentException - if the initial capacity is negative.

IdHashMap

public IdHashMap()

Constructs an empty HashMap with the default initial capacity (16) and the default load factor (0.75).
