Class Summary

BindingAssigner	Assigns values to variables based on a supplied set of bindings.
CompareOptimizer	A query optimizer that replaces Compare operators with SameTerms, if possible.
ConjunctiveConstraintSplitter	Splits conjunctive constraints into seperate constraints.
ConstantOptimizer	A query optimizer that optimizes constant value expressions.
DisjunctiveConstraintOptimizer	A query optimizer that optimize disjunctive constraints on tuple expressions.
EvaluationStatistics	Supplies various query model statistics to the query engine/optimizer.
EvaluationStatistics.CardinalityCalculator
EvaluationStrategyImpl	Evaluates the TupleExpr and ValueExpr using Iterators and common tripleSource API.
FilterOptimizer	Optimizes a query model by pushing Filters as far down in the model tree as possible.
QueryJoinOptimizer	A query optimizer that re-orders nested Joins.
QueryModelPruner	A query optimizer that prunes query model trees by removing superfluous parts and/or by reducing complex parts with simpler parts.
SameTermFilterOptimizer	A query optimizer that embeds Filters with SameTerm operators in statement patterns as much as possible.
