org.openrdf.query.algebra.evaluation.QueryBindingSet

All Implemented Interfaces:

Serializable, Iterable<Binding>, BindingSet

public class QueryBindingSet
extends Object
implements BindingSet

An implementation of the BindingSet interface that is used to evalate query object models. This implementations differs from MapBindingSet in that it maps variable names to Value objects and that the Binding objects are created lazily.
