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

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

Modifier and Type	Class and Description
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	TransformFilterConjunction Redo FILTER (A&&B) as FILTER(A) FILTER(B) (as an expr list).
class	TransformFilterDisjunction Filter disjunction.
class	TransformFilterEquality
class	TransformFilterPlacement Rewrite an algebra expression to put filters as close to their bound variables in a BGP.
class	TransformJoinStrategy Choose join strategy
class	TransformMergeBGPs Merge adjacent BGPsTransformCollapseBGPs
class	TransformOrderByDistinctAppplication 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 BGPs to joins of triples.
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
