Class MemStatementIterator
java.lang.Object
org.eclipse.rdf4j.sail.memory.model.MemStatementIterator
- All Implemented Interfaces:
AutoCloseable,Iterator<MemStatement>,CloseableIteration<MemStatement>
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.
