WeakHashMap.HashIterator
WeakHashMap.HashIterator()
hasNext
public boolean hasNext()
- Description copied from interface:
Iterator
- Returns true if the iteration has more elements. (In other
words, returns true if next would return an element
rather than throwing an exception.)
- Specified by:
hasNext
in interface Iterator
- Returns:
- true if the iterator has more elements.
nextEntry
protected WeakHashMap.Entry nextEntry()
- The common parts of next() across different types of iterators
remove
public void remove()
- Description copied from interface:
Iterator
- Removes from the underlying collection the last element returned by the
iterator (optional operation). This method can be called only once per
call to next. The behavior of an iterator is unspecified if
the underlying collection is modified while the iteration is in
progress in any way other than by calling this method.
