Method Details

close

public void close()

close in interface CloseableIteration<E,X extends Exception>

Throws:

X extends Exception

hasNext

public boolean hasNext()
                throws X

true if the iteration has more elements.

Throws:

X

next

public E next()
       throws X

Throws:

X extends Exception

remove

public void remove()
            throws X
