Class AbstractHashedMap.HashEntry<K,​V>

  • Type Parameters:
    K - the type of the keys
    V - the type of the values
    All Implemented Interfaces:
    java.util.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 java.lang.Object
implements java.util.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.
