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