Public Class SimpleVirtualAlgebraOptimiser
	Inherits VirtualAlgebraOptimiser(Of Integer, Integer)

The 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 VirtualAlgebraOptimiserTNodeID, TGraphIDCreateVirtualNode(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 VirtualAlgebraOptimiserTNodeID, TGraphID.)
	IsApplicable(SparqlUpdateCommandSet)	Returns that the optimiser is applicable to all updates. (Inherited from VirtualAlgebraOptimiserTNodeID, 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 VirtualAlgebraOptimiserTNodeID, TGraphID.)
	SubstitutePrimaryExpression	Substitutes a primary expression which is a Node term for a virtual Node term. (Inherited from VirtualAlgebraOptimiserTNodeID, TGraphID.)
	ToString	Returns a string that represents the current object. (Inherited from Object.)
	Transform	Transforms an expression so Node terms are virtualised. (Inherited from VirtualAlgebraOptimiserTNodeID, TGraphID.)

Fields

	Name	Description
	_provider	Virtual RDF Provider. (Inherited from VirtualAlgebraOptimiserTNodeID, TGraphID.)
