Creates a new
TDoubleDoubleHashMap instance with a prime
capacity equal to or greater than initialCapacity and
with the default load factor. |
TDoubleDoubleHashMap(int initialCapacity,

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

Creates a new
TDoubleDoubleHashMap instance with the default
capacity and load factor. |
