Classes in org.eclipse.rdf4j.query.algebra.evaluation.optimizer used by org.eclipse.rdf4j.query.algebra.evaluation.optimizer

Class	Description
BindingAssignerOptimizer	Assigns values to variables based on a supplied set of bindings.
BindingSetAssignmentInlinerOptimizer	Optimizes a query model by inlining BindingSetAssignment values where possible.
CompareOptimizer	A query optimizer that replaces Compare operators with SameTerms, if possible.
ConjunctiveConstraintSplitterOptimizer	Splits conjunctive constraints into seperate constraints.
DisjunctiveConstraintOptimizer	A query optimizer that optimize disjunctive constraints on tuple expressions.
FilterOptimizer	Optimizes a query model by pushing Filters as far down in the model tree as possible.
IterativeEvaluationOptimizer
OrderLimitOptimizer	Moves the Order node above the Projection when variables are projected.
ParentReferenceCleaner	Cleans up QueryModelNode.getParentNode() references that have become inconsistent with the actual algebra tree structure due to optimization operations.
ProjectionRemovalOptimizer	If a projection node in the algebra does not contribute or change the results it can be removed from the tree.
QueryModelNormalizerOptimizer	A query optimizer that (partially) normalizes query models to a canonical form.
SameTermFilterOptimizer	A query optimizer that embeds Filters with SameTerm operators in statement patterns as much as possible.
UnionScopeChangeOptimizer	Inspect Union clauses to check if scope change can be avoided (allowing injection of pre-bound vars into union arguments).
