org.apache.commons.collections4.multimap.AbstractMultiValuedMap<K,V>

org.apache.commons.collections4.multimap.AbstractSetValuedMap<K,V>

org.apache.commons.collections4.multimap.LinkedHashSetValuedLinkedHashMap<K,V>

Type Parameters:

K - The type of the keys in this map

V - The type of the values in this map

All Implemented Interfaces:

Serializable, MultiValuedMap<K,V>, SetValuedMap<K,V>

public class LinkedHashSetValuedLinkedHashMap<K,V>
extends AbstractSetValuedMap<K,V>
implements Serializable

Implements a SetValuedMap, using a LinkedHashMap to provide data storage and LinkedHashSets as value collections. This is the standard implementation of a SetValuedMap.

Note that LinkedHashSetValuedLinkedHashMap is not synchronized and is not thread-safe. If you wish to use this map from multiple threads concurrently, you must use appropriate synchronization. This class may throw exceptions when accessed by concurrent threads without synchronization.

Since:

4.5.0-M3
