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