Class BlockIterState

java.lang.Object

org.aksw.jena_sparql_api.io.binseach.BlockIterState

public class BlockIterState
extends Object

A helper iterator that automatically closes the previous item when next() is called. Actually, we do not need next to return an object, instead it could just set properties directly: IterState.advance(); IterState.closeCurrent(); IterState.current();
