Public Class PropertyFunction
	Implements IUnaryOperator, ISparqlAlgebra

The PropertyFunction type exposes the following members.

Constructors

	Name	Description
	PropertyFunction	Creates a new Property function algebra.

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.
	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	Evaluates the algebra in the given 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	Throws an error because property functions cannot be converted back to graph patterns.
	ToQuery	Throws an error because property functions cannot be converted back to queries.
	ToString	Gets the string representation of the algebra. (Overrides ObjectToString.)
	Transform	Transforms this algebra with the given optimiser.
