Classes in org.eclipse.rdf4j.query.algebra.evaluation.impl that implement QueryOptimizer

Modifier and Type	Class and Description
class	BindingAssigner Assigns values to variables based on a supplied set of bindings.
class	BindingSetAssignmentInliner Optimizes a query model by inlining BindingSetAssignment values where possible.
class	CompareOptimizer A query optimizer that replaces Compare operators with SameTerms, if possible.
class	ConjunctiveConstraintSplitter Splits conjunctive constraints into seperate constraints.
class	ConstantOptimizer A query optimizer that optimizes constant value expressions.
class	DisjunctiveConstraintOptimizer A query optimizer that optimize disjunctive constraints on tuple expressions.
class	FilterOptimizer Optimizes a query model by pushing Filters as far down in the model tree as possible.
class	IterativeEvaluationOptimizer
class	OrderLimitOptimizer Moves the Order node above the Projection when variables are projected.
class	ParentReferenceCleaner Cleans up QueryModelNode.getParentNode() references that have become inconsistent with the actual algebra tree structure due to optimization operations.
class	QueryJoinOptimizer A query optimizer that re-orders nested Joins.
class	QueryModelNormalizer A query optimizer that (partially) normalizes query models to a canonical form.
class	QueryModelPruner Deprecated. Replaced by QueryModelNormalizer.
class	RegexAsStringFunctionOptimizer A query optimizer that replaces REGEX with FunctionCalls that are equivalent operators
class	SameTermFilterOptimizer A query optimizer that embeds Filters with SameTerm operators in statement patterns as much as possible.
class	UnionScopeChangeOptimizer Inspect Union clauses to check if scope change can be avoided (allowing injection of pre-bound vars into union arguments).
