    • get

      public java.lang.Object get(short key)
      Description copied from interface: ShortObjectMap
      Gets the value in the map with the specified key.
      Specified by:
      get in interface ShortObjectMap<java.lang.Object>
      Parameters:
      key - the key whose associated value is to be returned.
      Returns:
      the value or null if the key was not found in the map.

    • put

      public java.lang.Object put(short key, java.lang.Object value)
      Description copied from interface: ShortObjectMap
      Puts the given entry into the map.
      Specified by:
      put in interface ShortObjectMap<java.lang.Object>
      Parameters:
      key - the key of the entry.
      value - the value of the entry.
      Returns:
      the previous value for this key or null if there was no previous mapping.

    • remove

      public java.lang.Object remove(short key)
      Description copied from interface: ShortObjectMap
      Removes the entry with the specified key.
      Specified by:
      remove in interface ShortObjectMap<java.lang.Object>
      Parameters:
      key - the key for the entry to be removed from this map.
      Returns:
      the previous value for the key, or null if there was no mapping.

      Description copied from interface: ShortObjectMap
      Gets an iterable to traverse over the primitive entries contained in this map. As an optimization, the ShortObjectMap.PrimitiveEntrys returned by the
      invalid reference 
      Iterator
      may change as the
      invalid reference 
      Iterator
      progresses. The caller should not rely on ShortObjectMap.PrimitiveEntry key/value stability.
