The SingleValueRestrictionFilter type exposes the following members.

Constructors

	Name	Description
	SingleValueRestrictionFilter	Creates a new Single Value Restriction Filter.

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 VariableRestrictionFilter.)
	FloatingVariables	Gets the enumeration of floating variables in the algebra i.e. variables that are not guaranteed to have a bound value. (Inherited from VariableRestrictionFilter.)
	InnerAlgebra	Gets the Inner Algebra. (Inherited from VariableRestrictionFilter.)
	RestrictionValue	Gets the Value Restriction which this filter applies.
	RestrictionVariable	Gets the Variable that this filter restricts the value of. (Inherited from VariableRestrictionFilter.)
	SparqlFilter	Gets the Filter to be used. (Inherited from VariableRestrictionFilter.)
	Variables	Gets the Variables used in the Algebra. (Inherited from VariableRestrictionFilter.)

Methods

	Name	Description
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object.)
	Evaluate	Applies the Filter over the results of evaluating the inner pattern. (Overrides VariableRestrictionFilterEvaluate(SparqlEvaluationContext).)
	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.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	ToGraphPattern	Converts the Algebra back to a Graph Pattern. (Inherited from VariableRestrictionFilter.)
	ToQuery	Converts the Algebra back to a SPARQL Query. (Inherited from VariableRestrictionFilter.)
	ToString	Gets the String representation of the FILTER. (Inherited from VariableRestrictionFilter.)
	Transform	Transforms the Inner Algebra using the given Optimiser. (Inherited from VariableRestrictionFilter.)
