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

Method Summary | |
---|---|
Object | clone() |
int | computeHashCode(float val)
Default implementation of TFloatHashingStrategy:
delegates hashing to HashFunctions.hash(float).
|
boolean | contains(float val)
Searches the set for val
|
boolean | forEach(TFloatProcedure procedure)
Executes procedure for each element in the set.
|
protected int | index(float val)
Locates the index of val.
|
protected int | insertionIndex(float val)
Locates the index at which val can be inserted. if
there is already a value equal()ing val in the set,
returns that value as a negative integer.
|
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.
