Constructor Detail

SimpleMapImpl

public SimpleMapImpl()

Construct a SimpleMapImpl using a BinaryRadixTree as the internal storage.

SimpleMapImpl

public SimpleMapImpl(BinaryLongMap blm)

Construct a SimpleMapImpl around an existing BinaryLongMap.

Parameters:

blm - the BinaryLongMap to use as the storage for this map

Method Detail

clear

public void clear()

Clear all key/value mappings.

Specified by:

clear in interface Map

Overrides:

clear in class AbstractKeyBasedMap

containsKey

public boolean containsKey(Object oKey)

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

Specified by:

containsKey in interface Map

Overrides:

containsKey in class AbstractKeyBasedMap

Returns:

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

get

public Long get(Object oKey)

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

Specified by:

get in interface 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

put

public Long put(Object oKey,
                Object oValue)

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

Specified by:

put in interface 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 Long remove(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 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 Map

Overrides:

size in class AbstractKeyBasedMap

Returns:

the number of key-value mappings in this map

iterateKeys

protected 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
