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