Classes in org.eclipse.rdf4j.query.algebra.evaluation.optimizer that implement QueryOptimizerModifier and TypeClassDescriptionclassAssigns values to variables based on a supplied set of bindings.classOptimizes a query model by inliningBindingSetAssignmentvalues where possible.classclassSplits conjunctive constraints into seperate constraints.classA query optimizer that optimizes constant value expressions.classA query optimizer that optimize disjunctive constraints on tuple expressions.classOptimizes a query model by pushingFilters as far down in the model tree as possible.classclassMoves the Order node above the Projection when variables are projected.classChecksQueryModelNode.getParentNode()references that have become inconsistent with the actual algebra tree structure due to optimization operations.classCleans upQueryModelNode.getParentNode()references that have become inconsistent with the actual algebra tree structure due to optimization operations.classIf a projection node in the algebra does not contribute or change the results it can be removed from the tree.classA query optimizer that re-orders nested Joins.classA query optimizer that (partially) normalizes query models to a canonical form.classA query optimizer that replaces REGEX withFunctionCalls that are equivalent operatorsclassclassInspect Union clauses to check if scope change can be avoided (allowing injection of pre-bound vars into union arguments).Methods in org.eclipse.rdf4j.query.algebra.evaluation.optimizer that return types with arguments of type QueryOptimizerConstructors in org.eclipse.rdf4j.query.algebra.evaluation.optimizer with parameters of type QueryOptimizer
