Constructor Detail

CloseableIteratorIteration

public CloseableIteratorIteration()

Creates an uninitialized CloseableIteratorIteration, needs to be initialized by calling setIterator(Iterator) before it can be used.

CloseableIteratorIteration

public CloseableIteratorIteration(Iterator<? extends E> iter)

Creates a CloseableIteratorIteration that wraps the supplied iterator.

Method Detail

setIterator

protected void setIterator(Iterator<? extends E> iter)

hasNext

public boolean hasNext()
                throws X extends Exception

Description copied from interface: Iteration

Returns true if the iteration has more elements. (In other words, returns true if Iteration.next() would return an element rather than throwing a NoSuchElementException.)

Returns:

true if the iteration has more elements.

Throws:

X

X extends Exception

next

public E next()
       throws X extends Exception

Description copied from interface: Iteration

Returns the next element in the iteration.

Returns:

the next element in the iteration.

Throws:

X extends Exception

remove

public void remove()
            throws X extends Exception

Description copied from interface: Iteration

Removes from the underlying collection the last element returned by the iteration (optional operation). This method can be called only once per call to next.

Throws:

X extends Exception
