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.

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.
void	remove(Binary binKey) Blindly remove the specified Binary key from the map.
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.

Constructor Detail

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 Detail

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
