SyntaxThe SimpleVirtualAlgebraOptimiser type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | SimpleVirtualAlgebraOptimiser |
Creates a new Simple Virtual Algebra Optimiser.
|
Methods| Name | Description | |
|---|---|---|
 | CreateVirtualNode |
Creates a new Virtual Node using the virtual RDF provider this optimiser was instantiated with.
(Overrides VirtualAlgebraOptimiser<TNodeID, TGraphID>.CreateVirtualNode(TNodeID, INode).) |
| Equals | Determines whether the specified object is equal to the current object. (Inherited from Object.) |
| Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
| GetHashCode | Serves as the default hash function. (Inherited from Object.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| IsApplicable(SparqlQuery) |
Returns that the optimiser is applicable to all queries.
(Inherited from VirtualAlgebraOptimiser<TNodeID, TGraphID>.) |
| IsApplicable(SparqlUpdateCommandSet) |
Returns that the optimiser is applicable to all updates.
(Inherited from VirtualAlgebraOptimiser<TNodeID, TGraphID>.) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
| Optimise |
Optimises the algebra so that all Node terms are virtualised.
(Inherited from VirtualAlgebraOptimiser<TNodeID, TGraphID>.) |
| SubstitutePrimaryExpression |
Substitutes a primary expression which is a Node term for a virtual Node term.
(Inherited from VirtualAlgebraOptimiser<TNodeID, TGraphID>.) |
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
| Transform |
Transforms an expression so Node terms are virtualised.
(Inherited from VirtualAlgebraOptimiser<TNodeID, TGraphID>.) |
Fields| Name | Description | |
|---|---|---|
 | _provider |
Virtual RDF Provider.
(Inherited from VirtualAlgebraOptimiser<TNodeID, TGraphID>.) |
