org.openorb.util.WeakHashSet
A weak set. This does not prevent it's members being reclaimed by the garbage collector.
Constructor Summary | |
---|---|
WeakHashSet()
Constructs a new, empty set; the backing WeakHashMap instance has default capacity and load factor, which is 0.75. |
|
WeakHashSet(java.util.Collection c)
Constructs a new set containing the elements in the specified collection. |
|
WeakHashSet(int initialCapacity)
Constructs a new, empty set; the backing WeakHashMap instance has the specified initial capacity and default load factor, which is 0.75. |
|
WeakHashSet(int initialCapacity,
float loadFactor)
Constructs a new, empty set; the backing WeakHashMap instance has the specified initial capacity and the specified load factor. |
