All Implemented Interfaces:
BinaryLongMap
Enclosing class:
MultiBinaryLongMap.PrimaryBinaryLongMap
protected class MultiBinaryLongMap.PrimaryBinaryLongMap.CompressedPrimaryBinaryLongMap extends MultiBinaryLongMap.SafeBinaryLongMap
The CompressedPrimaryBinaryLongMap is a trivial "Safe" wrapper around the main key-tree, which associates keys to their single (primary) long value.

  • Constructor Details

    • CompressedPrimaryBinaryLongMap

      public CompressedPrimaryBinaryLongMap(BinaryLongMap blmKeyTree, ReentrantReadWriteLock rwLock)
      Construct a CompressedPrimaryBinaryLongMap.
      Parameters:
      blmKeyTree - the BinaryLongMap holding the keys for the outer MultiBinaryLongMap
      rwLock - the master ReadWriteReentrantLock

  • Method Details

    • put

      public void put(Binary binKey, long lValue)
      Blindly store the passed value for the specified key, adding the key if it is not already in the map, or replacing the current value if the key is in the map.

      Note that associating the value zero with a key is analogous to removing the key.

      Specified by:
      put in interface BinaryLongMap
      Overrides:
      put in class MultiBinaryLongMap.SafeBinaryLongMap
      Parameters:
      binKey - the Binary key to add or update
      lValue - the value to associate with the key

    • putIfAbsent

      public boolean putIfAbsent(Binary binKey, long lValue)
      Store the passed value for the specified key, only if the key does not currently exist in the map.

      Note that associating the value zero with a key using this method will have no effect, since were that key already present, there would be no change, and were it not present, the value zero is analogous to removing the key, which again is no change (since it is not present).

      Specified by:
      putIfAbsent in interface BinaryLongMap
      Overrides:
      putIfAbsent in class MultiBinaryLongMap.SafeBinaryLongMap
      Parameters:
      binKey - a Binary key
      lValue - the new value to associate with the passed key
      Returns:
      true iff the key was not present in the map, and now it is present in the map associated with the passed value

    • remove

      public void remove(Binary binKey)
      Blindly remove the specified Binary key from the map.
      Specified by:
      remove in interface BinaryLongMap
      Overrides:
      remove in class MultiBinaryLongMap.SafeBinaryLongMap
      Parameters:
      binKey - a Binary key

    • remove

      public boolean remove(Binary binKey, long lValue)
      Remove the specified Binary key from the map iff it exists in the map and is associated with the specified value.

      Note that removing an association whose value is zero has no effect.

      Specified by:
      remove in interface BinaryLongMap
      Overrides:
      remove in class MultiBinaryLongMap.SafeBinaryLongMap
      Parameters:
      binKey - a Binary key
      lValue - the value that the key must have in order to be removed
      Returns:
      true iff the map contained the key, it was associated with the specified value, and has now been removed

    • clear

      public void clear()
      Initialize the map to an empty state.
      Specified by:
      clear in interface BinaryLongMap
      Overrides:
      clear in class MultiBinaryLongMap.SafeBinaryLongMap
