Constructor Detail

FastCopyHashSet

public FastCopyHashSet()

Constructs a new, empty set; the backing FastCopyHashMap instance has default initial capacity (16) and load factor (0.75).

FastCopyHashSet

public FastCopyHashSet(java.util.Collection<? extends E> c)

Constructs a new set containing the elements in the specified collection. The FastCopyHashMap is created with default load factor (0.75) and an initial capacity sufficient to contain the elements in the specified collection.

Parameters:

c - the collection whose elements are to be placed into this set.

Throws:

java.lang.NullPointerException - if the specified collection is null.

FastCopyHashSet

public FastCopyHashSet(int initialCapacity,
                       float loadFactor)

Constructs a new, empty set; the backing FastCopyHashMap instance has the specified initial capacity and the specified load factor.

Parameters:

initialCapacity - the initial capacity. The implementation performs internal sizing to accommodate this many elements.

loadFactor - the load factor threshold, used to control resizing. Resizing may be performed when the average number of elements per bin exceeds this threshold.

Throws:

java.lang.IllegalArgumentException - if the initial capacity is less than zero, or if the load factor is nonpositive.

FastCopyHashSet

public FastCopyHashSet(int initialCapacity)

Constructs a new, empty set; the backing FastCopyHashMap instance has the specified initial capacity and default load factor, which is 0.75.

Parameters:

initialCapacity - the initial capacity of the hash table.

Throws:

java.lang.IllegalArgumentException - if the initial capacity is less than zero.
