Syntax

public class Slice : IUnaryOperator, ISparqlAlgebra

Public Class Slice
	Implements IUnaryOperator, ISparqlAlgebra

The Slice type exposes the following members.

Constructors

	Name	Description
	Slice(ISparqlAlgebra)	Creates a new Slice modifier which will detect LIMIT and OFFSET from the query.
	Slice(ISparqlAlgebra, Int32, Int32)	Creates a new Slice modifier which uses a specific LIMIT and OFFSET.

Properties

	Name	Description
	DetectFromQuery	Gets whether the Algebra will detect the Limit and Offset to use from the provided query.
	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.
	Limit	Gets the Limit in use (-1 indicates no Limit).
	Offset	Gets the Offset in use (0 indicates no Offset).
	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 Slice by applying the appropriate LIMIT and OFFSET to the Results.
	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 exception since a Slice() cannot be converted back to a Graph Pattern.
	ToQuery	Converts the Algebra back to a SPARQL Query.
	ToString	Gets the String representation of the Algebra. (Overrides ObjectToString.)
	Transform	Transforms the Inner Algebra using the given Optimiser.
