org.openrdf.query.algebra.evaluation.impl.SameTermFilterOptimizer
A query optimizer that embeds {@link Filter}s with {@link SameTerm} operatorsin statement patterns as much as possible. Operators like sameTerm(X, Y) are processed by renaming X to Y (or vice versa). Operators like sameTerm(X, ) are processed by assigning the URI to all occurring variables with name X. @author Arjohn Kampman @author James Leigh
