Class AbstractHashedMap.HashEntry<K,V>

java.lang.Object

org.apache.commons.collections4.map.AbstractHashedMap.HashEntry<K,V>

Type Parameters:

K - the type of the keys

V - the type of the values

All Implemented Interfaces:

Map.Entry<K,V>, KeyValue<K,V>

Direct Known Subclasses:

AbstractLinkedMap.LinkEntry, AbstractReferenceMap.ReferenceEntry

Enclosing class:

AbstractHashedMap<K,V>

protected static class AbstractHashedMap.HashEntry<K,V>
extends Object
implements Map.Entry<K,V>, KeyValue<K,V>

HashEntry used to store the data.

If you subclass AbstractHashedMap but not HashEntry then you will not be able to access the protected fields. The entryXxx() methods on AbstractHashedMap exist to provide the necessary access.
