hasNext
public boolean hasNext()
Deprecated.Description copied from class:IterationWrapperChecks whether the wrapped Iteration contains more elements, closing this Iteration when this is not the case.
-
next
public E next()
Deprecated.Description copied from class:IterationWrapperReturns the next element from the wrapped Iteration.
-
accept
protected abstract boolean accept(E object)
Deprecated.Tests whether or not the specified object should be returned by this Iteration. All objects from the wrapped Iteration pass through this method in the same order as they are coming from the wrapped Iteration.- Parameters:
object- The object to be tested.- Returns:
- true if the object should be returned, false otherwise.
- Throws:
X

handleClose
protected void handleClose()
Deprecated.Description copied from class:IterationWrapperCloses this Iteration and also closes the wrapped Iteration if it is aCloseableIteration.- Overrides:
