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