TObjectIntHashMap()
Creates a new
TObjectIntHashMap instance with the default
capacity and load factor. |
TObjectIntHashMap(int initialCapacity)
Creates a new
TObjectIntHashMap instance with a prime
capacity equal to or greater than initialCapacity and
with the default load factor. |
TObjectIntHashMap(int initialCapacity,
float loadFactor)
Creates a new
TObjectIntHashMap instance with a prime
capacity equal to or greater than initialCapacity and
with the specified load factor. |
TObjectIntHashMap(int initialCapacity,
float loadFactor,
TObjectHashingStrategy<K> strategy)
Creates a new
TObjectIntHashMap instance with a prime
value at or near the specified capacity and load factor. |
TObjectIntHashMap(int initialCapacity,
TObjectHashingStrategy<K> strategy)
Creates a new
TObjectIntHashMap instance whose capacity
is the next highest prime above initialCapacity + 1
unless that value is already prime. |
TObjectIntHashMap(TObjectHashingStrategy<K> strategy)
Creates a new
TObjectIntHashMap instance with the default
capacity and load factor. |
