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