-
getNextElement
public E getNextElement() throws X extends Exception
Description copied from class:LookAheadIteration
Gets the next element. Subclasses should implement this method so that it returns the next element.- Specified by:
getNextElement
in classLookAheadIteration<E,X extends Exception>
- Returns:
- The next element, or null if no more elements are available.
- Throws:
X extends Exception
-
handleClose
protected final void handleClose() throws X extends Exception
Description copied from class:AbstractCloseableIteration
Called byAbstractCloseableIteration.close()
when it is called for the first time. This method is only called once on each iteration. By default, this method does nothing.- Overrides:
handleClose
in classLookAheadIteration<E,X extends Exception>
- Throws:
