All Implemented Interfaces:

CloseableIteration<MemStatement,X>, Iteration<MemStatement,X>

public class MemStatementIterator<X extends Exception>
extends CloseableIterationBase<MemStatement,X>

A StatementIterator that can iterate over a list of Statement objects. This iterator compares Resource and Literal objects using the '==' operator, which is possible thanks to the extensive sharing of these objects in the MemoryStore.
