Method Detail
-
convert
protected abstract X convert(RuntimeException e)
Deprecated.Converts an exception from the underlying iteration to an exception of type X.
-
hasNext
public boolean hasNext()
Deprecated.Checks whether the underlying Iteration contains more elements.- Returns:
- true if the underlying Iteration contains more elements, false otherwise.
-
next
public E next()
Deprecated.Returns the next element from the wrapped Iteration.- Throws:
NoSuchElementException
- If all elements have been returned.IllegalStateException
- If the Iteration has been closed.
-
remove
public void remove()
Deprecated.Calls remove() on the underlying Iteration.- Throws:
UnsupportedOperationException
- If the wrapped Iteration does not support the remove operation.IllegalStateException
- If the Iteration has been closed, or ifnext()
has not yet been called, orremove()
has already been called after the last call tonext()
.
