public interface IAbstractJoin : ISparqlAlgebra

Public Interface IAbstractJoin
	Inherits ISparqlAlgebra

The IAbstractJoin type exposes the following members.

Properties

	Name	Description
	FixedVariables	Gets the enumeration of fixed variables in the algebra i.e. variables that are guaranteed to have a bound value. (Inherited from ISparqlAlgebra.)
	FloatingVariables	Gets the enumeration of floating variables in the algebra i.e. variables that are not guaranteed to have a bound value. (Inherited from ISparqlAlgebra.)
	Lhs	Gets the LHS of the Join.
	Rhs	Gets the RHS of the Join.
	Variables	Gets the enumeration of Variables used in the Algebra. (Inherited from ISparqlAlgebra.)

Methods

	Name	Description
	Evaluate	Evaluates the Algebra in the given Context. (Inherited from ISparqlAlgebra.)
	ToGraphPattern	Converts the Algebra back to a Graph Pattern. (Inherited from ISparqlAlgebra.)
	ToQuery	Converts the Algebra back to a SPARQL Query. (Inherited from ISparqlAlgebra.)
	Transform	Transforms both sides of the Join using the given Optimiser.
	TransformLhs	Transforms the LHS of the Join using the given Optimiser.
	TransformRhs	Transforms the RHS of the Join using the given Optimiser.

Remarks

Specific sub-interfaces are used to mark specific kinds of Join.
