Method Summary

Modifier and Type

Method

Description

static QueryIterator

create(Iterator<Binding> iter)

static QueryIterator

create(Iterator<Binding> iter, ExecutionContext execCxt)

void

output(org.apache.jena.atlas.io.IndentedWriter out, SerializationContext sCxt)

void

setIterator(Iterator<Binding> iterator)

Preferable to use a constructor - but sometimes that is inconvenient so pass null in the constructor and then call this before the iterator is used.
