Constructor Detail

HashMapTwoInts

public HashMapTwoInts(int initialCapacity,
                      float loadFactor)

Constructs a new, empty map with the specified initial capacity and the specified load factor.

Parameters:

initialCapacity - the initial capacity of the HashMap.

loadFactor - the load factor of the HashMap

Throws:

IllegalArgumentException - if the initial capacity is less than zero, or if the load factor is nonpositive.

HashMapTwoInts

public HashMapTwoInts(int initialCapacity)

Constructs a new, empty map with the specified initial capacity and default load factor.

Parameters:

initialCapacity - the initial capacity of the HashMap.

Throws:

IllegalArgumentException - if the initial capacity is less than zero.

HashMapTwoInts

public HashMapTwoInts()

Constructs a new, empty map with a default capacity and load factor.

HashMapTwoInts

public HashMapTwoInts(Map t)

Constructs a new map with the same mappings as the given map. The map is created with a capacity of twice the number of mappings in the given map or the default initial capacity (whichever is greater), and a default load factor.

Parameters:

t - the map whose mappings are to be placed in this map.

Method Detail

getNewEntry

protected HashMapPrimitive.Entry<K> getNewEntry(int hash,
                                                K key,
                                                HashMapPrimitive.Entry<K> next)

Gets a map entry for this type of map, containing a key and a pair of ints.

Overrides:

getNewEntry in class HashMapInt<K>

Parameters:

hash - the hash value of the specified key

key - the key for this map entry to wrap

next - the next pointer for this entry in its singly-linked list (can be null)

Returns:

a new HashMapPrimitive.Entry for this type of map
