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