## Class AbstractHashedMap.HashEntry

- java.lang.Object
- - org.apache.commons.collections.map.AbstractHashedMap.HashEntry

- All Implemented Interfaces:
    Map.Entry, KeyValue
  Direct Known Subclasses:
    AbstractLinkedMap.LinkEntry, AbstractReferenceMap.ReferenceEntry, IdentityMap.IdentityEntry
  Enclosing class:
    AbstractHashedMap

      protected static class AbstractHashedMap.HashEntry
      extends Object
      implements Map.Entry, KeyValue

  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.
