Constructor Details

WeakHashSet

public WeakHashSet()

WeakHashSet

public WeakHashSet(Collection<? extends T> c)

Constructs a new set containing the elements in the specified collection. The HashMap 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:

NullPointerException - if the specified collection is null

WeakHashSet

public WeakHashSet(int initialCapacity,
 float loadFactor)

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

Parameters:

initialCapacity - the initial capacity of the hash map

loadFactor - the load factor of the hash map

Throws:

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

WeakHashSet

public WeakHashSet(int initialCapacity)

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

Parameters:

initialCapacity - the initial capacity of the hash table

Throws:

IllegalArgumentException - if the initial capacity is less than zero
