capacity equal to or greater than initialCapacity and
with the default load factor. |
TLongDoubleHashMap(int initialCapacity,
float loadFactor)
Creates a new
TLongDoubleHashMap instance with a prime
capacity equal to or greater than initialCapacity and
with the specified load factor. |
TLongDoubleHashMap(int initialCapacity,

TLongHashingStrategy strategy)
Creates a new
TLongDoubleHashMap instance with a prime
value at or near the specified capacity and load factor. |
TLongDoubleHashMap(int initialCapacity,
TLongHashingStrategy strategy)
Creates a new
TLongDoubleHashMap instance whose capacity
is the next highest prime above initialCapacity + 1
unless that value is already prime. |
