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

TDoubleFloatHashMap(int initialCapacity, float loadFactor, TDoubleHashingStrategy strategy)
Creates a new TDoubleFloatHashMap instance with a prime
value at or near the specified capacity and load factor.
