Constructor Detail

PartitionSplittingBackingMap.MaskedPartitionMap

protected PartitionSplittingBackingMap.MaskedPartitionMap(PartitionSet partMask)

Construct MaskedPartitionMap based on the specified PartitionSet.

Parameters:

partMask - the partition set that indicates which backing maps are represented by this MaskedPartitionMap

Method Detail

get

public java.lang.Object 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

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

Returns:

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

isEmpty

public boolean isEmpty()

Returns true if this map contains no key-value mappings.

Specified by:

isEmpty in interface java.util.Map

Overrides:

isEmpty in class AbstractKeyBasedMap

Returns:

true if this map contains no key-value mappings

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
