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