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