Uses of TransformCopy in com.hp.hpl.jena.sparql.algebra.optimize

Subclasses of TransformCopy in com.hp.hpl.jena.sparql.algebra.optimize

class	TransformDistinctToReduced Transforms generic DISTINCT plus ORDER BY combinations to REDUCED plus ORDER BY which typically gives better performance and memory consumption because engines have to keep less data in-memory to evaluate it.
class	TransformExpandOneOf
class	TransformExtendCombine An optimizer that aims to combine multiple extend clauses together.
class	TransformFilterConjunction Redo FILTER (A&&B) as FILTER(A) FILTER(B) (as an expr list).
class	TransformFilterDisjunction Filter disjunction.
class	TransformFilterEquality A transform that aims to optimize queries where there is an equality constraint on a variable to speed up evaluation e.g
class	TransformFilterImplicitJoin Optimizer for transforming implicit joins.
class	TransformFilterInequality A transform that aims to optimize queries where there is an inequality constraint on a variable in an attempt to speed up evaluation e.g
class	TransformFilterPlacement Rewrite an algebra expression to put filters as close to their bound variables.
class	TransformFilterPlacementConservative Rewrite an algebra expression to put filters as close to their bound variables in a BGP.
class	TransformImplicitLeftJoin Optimizer for transforming implicit joins.
class	TransformJoinStrategy Choose join strategy
class	TransformMergeBGPs Merge adjacent BGPsTransformCollapseBGPs
class	TransformOrderByDistinctApplication Improved optimization for ORDER BY plus DISTINCT or REDUCED combinations, see JENA-441 for original proposal and discussion.
class	TransformPathFlattern Perform the equivalent of the trasnactions in the SPARQL 1.1 spec.
class	TransformPathFlatternStd The path transformation step exactly as per the SPARQL 1.1 spec.
class	TransformPattern2Join Expand to joins of triples and quads.
class	TransformPromoteTableEmpty Optimizer that ensures that table empty is promoted as high up a query as is possible
class	TransformPropertyFunction Rewrite to replace a property function property with the call to the property function implementation
class	TransformRemoveLabels
class	TransformReorder A Transformer that applies a reordering to all BGPs and Quad Patterns present in the algebra
class	TransformSimplify
class	TransformTopN Optimization that changes queries that uses OFFSET/LIMIT and ORDER BY to execute using Top N: i.e.
