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