Method Details

hasNext

public boolean hasNext()
                throws SailException

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.)

Specified by:

hasNext in interface Iteration<MemStatement, SailException>

Returns:

true if the iteration has more elements.

Throws:

SailException

next

public MemStatement next()
                  throws SailException

Description copied from interface: Iteration

Returns the next element in the iteration.

Specified by:

next in interface Iteration<MemStatement, SailException>

Returns:

the next element in the iteration.

Throws:

SailException

remove

public void remove()
            throws SailException

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.

Specified by:

remove in interface Iteration<MemStatement, SailException>

Throws:

SailException

close

public final void close()
                 throws SailException

Description copied from interface: CloseableIteration

Closes this iteration, freeing any resources that it is holding. If the iteration has already been closed then invoking this method has no effect.

Specified by:

close in interface AutoCloseable

Specified by:

close in interface CloseableIteration<MemStatement, SailException>

Throws:

SailException
