Uses of TupleExpr in org.openrdf.query.algebra

Classes in org.openrdf.query.algebra that implement TupleExpr

Modifier and Type	Class and Description
class	ArbitraryLengthPath A tuple expression that matches a path of arbitrary length against an RDF graph.
class	BinaryTupleOperator An abstract superclass for binary tuple operators which, by definition, has two arguments.
class	BindingSetAssignment
class	DescribeOperator
class	Difference The MINUS set operator, which returns the result of the left tuple expression, except for the results that are also returned by the right tuple expression.
class	Distinct
class	EmptySet A tuple expression that contains zero solutions.
class	Extension An extension operator that can be used to add bindings to solutions whose values are defined by value expressions.
class	Filter The FILTER operator, as defined in SPARQL Query Language for RDF.
class	Group A tuple operator that groups tuples that have a specific set of equivalent variable bindings, and that can apply aggregate functions on the grouped results.
class	Intersection The INTERSECT set operator, which returns the intersection of the result sets of two tuple expressions.
class	Join A natural join between two tuple expressions.
class	LeftJoin The LeftJoin operator, as defined in SPARQL Query Language for RDF.
class	MultiProjection A "multi-projection" that can produce multiple solutions from a single set of bindings.
class	Order An order operator that can be used to order bindings as specified by a set of value expressions.
class	Projection A generalized projection (allowing the bindings to be renamed) on a tuple expression.
class	QueryRoot A semantics-less query model node that is used as the root of query model trees.
class	Reduced
class	Service The SERVICE keyword as defined in SERVICE definition.
class	SingletonSet A tuple expression that contains exactly one solution with zero bindings.
class	Slice The SLICE operator, as defined in SPARQL Query Language for RDF.
class	StatementPattern A tuple expression that matches a statement pattern against an RDF graph.
class	UnaryTupleOperator An abstract superclass for unary tuple operators which, by definition, has one argument.
class	Union The UNION set operator, which return the union of the result sets of two tuple expressions.
class	ZeroLengthPath A tuple expression that matches a path of length zero against an RDF graph.
