Constructor Detail

VolatileHashMap.KeyIterator

private VolatileHashMap.KeyIterator()

Method Detail

next

public java.lang.Object next()

Description copied from interface: java.util.Iterator

Obtain the next element in the collection.

---

hasNext

public boolean hasNext()

Description copied from interface: java.util.Iterator

Tests whether there are elements remaining in the collection. In other words, calling next() will not throw an exception.

Specified by:

hasNext in interface java.util.Iterator

---

nextEntry

protected VolatileHashMap.Entry nextEntry()

The common parts of next() across different types of iterators

---

remove

public void remove()

Description copied from interface: java.util.Iterator

Remove from the underlying collection the last element returned by next (optional operation). This method can be called only once after each call to next(). It does not affect what will be returned by subsequent calls to next.

Specified by:
