  BaseDeclProcessor | Resolves relative URIs in a query model using either an external base URI or using the base URI specified in the query model itself.
  BlankNodeVarProcessor | Processes blank nodes in the query body, replacing them with variables while retaining scope.
  ComplexSPARQLQueryTest | A set of compliance tests on SPARQL query functionality which can not be easily executed using the `SPARQL11ManifestTest` format.
  ConstructorBuilder |
  DatasetDeclProcessor | Extracts a SPARQL `Dataset` from an ASTQueryContainer, if one is contained.
  GraphPattern | A graph pattern consisting of (required and optional) tuple expressions, binding assignments and boolean constraints.
  PrefixDeclProcessor | Processes the prefix declarations in a SPARQL query model.
  PropertySetElem | Deprecated since 3.0.
  SPARQLDataSet |
  SPARQLParser |
  SPARQLParserFactory | A `QueryParserFactory` for SPARQL parsers.
  SPARQLQueries | Utility functions for working with SPARQL query strings.
  SPARQLUpdateDataBlockParser | An extension of `TriGStarParser` that processes data in the format specified in the SPARQL 1.1 grammar for Quad data (assuming no variables, as is the case for INSERT DATA and DELETE DATA operations).
  SPARQLUpdateTest | Tests for SPARQL 1.1 Update functionality.
  SPARQLUtil | Deprecated since 3.6.0 Use `SPARQLQueries` instead.
  StringEscapesProcessor | Processes escape sequences in strings, replacing the escape sequence with their actual value.
