ClassDescriptionUtilities to produce SPARQL algebraClass used to compile SPARQL queries into SPARQL algebra.Helper class for converting an algebra expression into a quad formConvert an Op expression in SPARQL syntax, that is, the reverse of algebra generation.Manage extension algebra operationsFunctions relating to
Ops.Get vars for a patternA visitor helper that maps all visits to a few general onesApply a visitor to the whole structure of Ops, recursively.One step in the transformation process.A bottom-top application of a transformation of SPARQL algebraRename quad form alegbraTransform that rewrites an algebra into quadblock formTransform that rewrites an algebra into quad formSpecial purpose base class for a single transformation.Convert query in algebra form so that the default graph of the query is the union of named graphsWrap another transform and pass on the transform operation
