Constructors

	Name	Description
	VariableRestrictionFilter	Creates a new Variable 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.
	FloatingVariables	Gets the enumeration of floating variables in the algebra i.e. variables that are not guaranteed to have a bound value.
	InnerAlgebra	Gets the Inner Algebra.
	RestrictionVariable	Gets the Variable that this filter restricts the value of.
	SparqlFilter	Gets the Filter to be used.
	Variables	Gets the Variables used in the Algebra.

Methods

	Name	Description
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object.)
	Evaluate	Evalutes the algebra for the given evaluation context.
	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.
	ToQuery	Converts the Algebra back to a SPARQL Query.
	ToString	Gets the String representation of the FILTER. (Overrides ObjectToString.)
	Transform	Transforms the Inner Algebra using the given Optimiser.
