SyntaxThe IExistsJoin 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.
(Inherited from IAbstractJoin.) |
| MustExist |
Gets whether the Join requires compatible solutions to exist on the RHS.
|
| Rhs |
Gets the RHS of the Join.
(Inherited from IAbstractJoin.) |
| Variables |
Gets the enumeration of Variables used in the Algebra.
