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

contains(byte val)
Searches the set for val
|
boolean |
forEach(TByteProcedure procedure)
Executes procedure for each element in the set.
|
protected int |
index(byte val)
Locates the index of val.
|
protected int |
insertionIndex(byte val)
Locates the index at which val can be inserted.
|
protected void |
removeAt(int index)
Releases the element currently stored at index.
|
protected int |
setUp(int initialCapacity)
initializes the hashtable to a prime capacity which is at least
initialCapacity + 1.
