## IExistsJoin Interface |

Represents an Algebra construct which is an Exists Join.

Syntax

The 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.
(Inherited from ISparqlAlgebra.) |
