Syntax

public interface IValuedNode : INode, IComparable<INode>, IComparable<IBlankNode>, IComparable<IGraphLiteralNode>, IComparable<ILiteralNode>, IComparable<IUriNode>, IComparable<IVariableNode>, IComparable<IRefNode>, IComparable<ITripleNode>, IEquatable<INode>, IEquatable<IBlankNode>, IEquatable<IGraphLiteralNode>, IEquatable<ILiteralNode>, IEquatable<IUriNode>, IEquatable<IVariableNode>, IEquatable<IRefNode>, IEquatable<ITripleNode>

Remarks

This interface extends the basic INode interface with methods related to turning the lexical value into a strongly typed .Net value. It is intended primarily for use within SPARQL expression evaluation where we need to do a lot of value conversions and currently waste a lot of effort (and thus performance) doing that.

Properties

EffectiveType

Gets the URI of the datatype this valued node represents as a String.

Declaration

string EffectiveType { get; }

Property Value

Type	Description
string

Remarks

Either String.Empty if no type or the string form of the type URI.

NumericType

Gets the Numeric Type of the Node.

Declaration

SparqlNumericType NumericType { get; }

Property Value

Type	Description
SparqlNumericType

Remarks

This interface extends the basic INode interface with methods related to turning the lexical value into a strongly typed .Net value. It is intended primarily for use within SPARQL expression evaluation where we need to do a lot of value conversions and currently waste a lot of effort (and thus performance) doing that.

Methods

AsBoolean()

Gets the Boolean value of the Node.

Declaration

bool AsBoolean()

Returns

Type	Description
System.Boolean

Remarks

This interface extends the basic INode interface with methods related to turning the lexical value into a strongly typed .Net value. It is intended primarily for use within SPARQL expression evaluation where we need to do a lot of value conversions and currently waste a lot of effort (and thus performance) doing that.

Exceptions

Type	Condition
RdfQueryException	Thrown if the Node cannot be converted to a Boolean.

AsDateTime()

Gets the Date Time value of the Node.

Declaration

DateTime AsDateTime()

Returns

Type	Description
System.DateTime

Remarks

Exceptions

Type	Condition
RdfQueryException	Thrown if the Node cannot be converted to a Date Time.

AsDateTimeOffset()

Gets the Date Time Offset value of the Node.

Declaration

DateTimeOffset AsDateTimeOffset()

Returns

Type	Description
System.DateTimeOffset

Remarks

This interface extends the basic INode interface with methods related to turning the lexical value into a strongly typed .Net value. It is intended primarily for use within SPARQL expression evaluation where we need to do a lot of value conversions and currently waste a lot of effort (and thus performance) doing that.

Exceptions

Type	Condition
RdfQueryException	Thrown if the Node cannot be converted to a Date Time Offset.

AsDecimal()

Gets the Decimal value of the Node.

Declaration

decimal AsDecimal()

Returns

Type	Description
decimal

Remarks

This interface extends the basic INode interface with methods related to turning the lexical value into a strongly typed .Net value. It is intended primarily for use within SPARQL expression evaluation where we need to do a lot of value conversions and currently waste a lot of effort (and thus performance) doing that.

Exceptions

Type	Condition
RdfQueryException	Thrown if the Node cannot be converted to a Decimal.

AsDouble()

Gets the Double value of the Node.

Declaration

double AsDouble()

Returns

Type	Description
double

Remarks

This interface extends the basic INode interface with methods related to turning the lexical value into a strongly typed .Net value. It is intended primarily for use within SPARQL expression evaluation where we need to do a lot of value conversions and currently waste a lot of effort (and thus performance) doing that.

Exceptions

Type	Condition
RdfQueryException	Thrown if the Node cannot be converted to a Double.

AsFloat()

Gets the Float value of the Node.

Declaration

float AsFloat()

Returns

Type	Description
float

Remarks

This interface extends the basic INode interface with methods related to turning the lexical value into a strongly typed .Net value. It is intended primarily for use within SPARQL expression evaluation where we need to do a lot of value conversions and currently waste a lot of effort (and thus performance) doing that.

Exceptions

Type	Condition
RdfQueryException	Thrown if the Node cannot be converted to a Float.

AsInteger()

Gets the Long value of the Node.

Declaration

long AsInteger()

Returns

Type	Description
long

Remarks

This interface extends the basic INode interface with methods related to turning the lexical value into a strongly typed .Net value. It is intended primarily for use within SPARQL expression evaluation where we need to do a lot of value conversions and currently waste a lot of effort (and thus performance) doing that.

Exceptions

Type	Condition
RdfQueryException	Thrown if the Node cannot be converted to a Long.

AsString()

Gets the String value of the Node.

Declaration

string AsString()

Returns

Type	Description
string

Remarks

This is distinct from ToString() because that method will typically include additional information like language specifier/datatype as appropriate whereas this method is used to produce a string as would be produced by applying the STR() function from SPARQL.

AsTimeSpan()

Gets the Time Span value of the Node.

Declaration

TimeSpan AsTimeSpan()

Returns

Type	Description
System.TimeSpan

Remarks

This interface extends the basic INode interface with methods related to turning the lexical value into a strongly typed .Net value. It is intended primarily for use within SPARQL expression evaluation where we need to do a lot of value conversions and currently waste a lot of effort (and thus performance) doing that.
