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