Constructor Detail

BinaryRadixTree.BinaryLongMap

public BinaryRadixTree.BinaryLongMap()

Method Detail

clear

public void clear()

Clear all key/value mappings.

Specified by:

clear in interface java.util.Map

Overrides:

clear in class AbstractKeyBasedMap

containsKey

public boolean containsKey(java.lang.Object oKey)

Returns true if this map contains a mapping for the specified key.

Specified by:

containsKey in interface java.util.Map

Overrides:

containsKey in class AbstractKeyBasedMap

Parameters:

oKey - key whose presence in this map is to be tested.

Returns:

true if this map contains a mapping for the specified key, false otherwise.

get

public java.lang.Long get(java.lang.Object oKey)

Returns the value to which this map maps the specified key.

Specified by:

get in interface java.util.Map

Specified by:

get in class AbstractKeyBasedMap

Parameters:

oKey - the key object

Returns:

the value to which this map maps the specified key, or null if the map contains no mapping for this key

See Also:

Map.containsKey(Object)

put

public java.lang.Long put(java.lang.Object oKey,
                          java.lang.Object oValue)

Associates the specified value with the specified key in this map.

Specified by:

put in interface java.util.Map

Overrides:

put in class AbstractKeyBasedMap

Parameters:

oKey - key with which the specified value is to be associated

oValue - value to be associated with the specified key

Returns:

previous value associated with specified key, or null if there was no mapping for key

remove

public java.lang.Long remove(java.lang.Object oKey)

Removes the mapping for this key from this map if present. Expensive: updates both the underlying cache and the local cache.

Specified by:

remove in interface java.util.Map

Overrides:

remove in class AbstractKeyBasedMap

Parameters:

oKey - key whose mapping is to be removed from the map

Returns:

previous value associated with specified key, or null if there was no mapping for key. A null return can also indicate that the map previously associated null with the specified key, if the implementation supports null values.

size

public int size()

Returns the number of key-value mappings in this map.

Specified by:

size in interface java.util.Map

Overrides:

size in class AbstractKeyBasedMap

Returns:

the number of key-value mappings in this map

iterateKeys

protected java.util.Iterator iterateKeys()

Create an iterator over the keys in this Map. The Iterator must support remove() if the Map supports removal.

Specified by:

iterateKeys in class AbstractKeyBasedMap

Returns:

a new instance of an Iterator over the keys in this Map
