SailBaseIteration

public SailBaseIteration(CloseableIteration<? extends T, ? extends E> iter,
 AbstractSailConnection connection)

Creates a new memory-store specific iteration object.

Parameters:

iter - the wrapped iteration over sail objects.

connection - the connection from which this iteration originates.

Method Details

hasNext

public boolean hasNext()
                throws E

Description copied from class: IterationWrapper

Checks whether the wrapped Iteration contains more elements, closing this Iteration when this is not the case.

Specified by:

hasNext in interface Iteration<T, E extends Exception>

Overrides:

hasNext in class IterationWrapper<T, E extends Exception>

Returns:

true if the wrapped Iteration contains more elements, false otherwise.

Throws:

E

handleClose

Overrides:

handleClose in class IterationWrapper<T, E extends Exception>

Throws:

E

forceClose

@Deprecated
protected void forceClose()
                   throws E

Deprecated.

Throws:
