Constructor Detail

HashBiMap

public HashBiMap(int initialCapacity,
                 float loadFactor)

Constructs an empty HashBiMap with the specified initial capacity and load factor.

Parameters:

initialCapacity - The initial capacity.

loadFactor - The load factor.

Throws:

IllegalArgumentException - If the initial capacity is negative or the load factor is nonpositive.

HashBiMap

public HashBiMap(int initialCapacity)

Constructs an empty HashBiMap with the specified initial capacity and the default load factor (0.75).

Parameters:

initialCapacity - The initial capacity.

Throws:

IllegalArgumentException - If the initial capacity is negative.

HashBiMap

public HashBiMap(Map<? extends K,? extends V> m)

Constructs a new HashBiMap with the same mappings as the specified Map. The HashBiMap is created with default load factor (0.75) and an initial capacity sufficient to hold the mappings in the specified Map.

Parameters:

m - The map whose mappings are to be placed in this map.

Throws:

NullPointerException - If the specified map is null.

HashBiMap

public HashBiMap()

Constructs an empty HashBiMap with the default initial capacity (16) and the default load factor (0.75).

HashBiMap

protected HashBiMap(boolean empty)

Creates an empty instance.

Parameters:

empty - Ignored parameter.

Method Detail

newEmptyReverseMap

protected BiMap<V,K> newEmptyReverseMap()

Description copied from class: BiMap

Returns a new instance of an empty reverse subclass of BiMap.

Specified by:

newEmptyReverseMap in class BiMap<K,V>

Returns:

A new instance of an empty reverse subclass of BiMap.

clone

public HashBiMap<K,V> clone()

Overrides:

clone in class AbstractMap<K,V>
