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

computeHashCode(double val)
Default implementation of TDoubleHashingStrategy:
delegates hashing to HashFunctions.hash(double).
|
boolean |
contains(double val)
Searches the set for val
|
boolean |
forEach(TDoubleProcedure procedure)
Executes procedure for each element in the set.
|
protected int |
index(double val)
Locates the index of val.
|
protected int |
insertionIndex(double 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.
