Parameters:

array - an array of short primitives

TShortHashSet

public TShortHashSet(TShortHashingStrategy strategy)

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

Parameters:

strategy - used to compute hash codes and to compare keys.

TShortHashSet

public TShortHashSet(int initialCapacity,
                     TShortHashingStrategy strategy)
