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