ReadOnlyIterator | public ReadOnlyIterator(Iterator base)(Code) | | Creates a read-only iterator.
Parameters: base - the base iterator. |
hasNext | public boolean hasNext()(Code) | | Returns true if the iteration has more elements. (In other words, returns
true if next would return an element rather than throwing an
exception.)
true if the iterator has more elements. |
next | public Object next()(Code) | | Returns the next element in the iteration.
the next element in the iteration. |
remove | public void remove()(Code) | | 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.
throws: UnsupportedOperationException - if the remove operation is notsupported by this Iterator. throws: IllegalStateException - if the next method has not yet beencalled, or the remove method hasalready been called after the last call to thenext method. |
