Syntax

public static class EqualityHelper

Properties

LiteralEqualityMode

Gets/Sets the Mode used to compute Literal Equality (Default is Strict which enforces the W3C RDF Specification).

Declaration

public static LiteralEqualityMode LiteralEqualityMode { get; set; }

Property Value

Type	Description
LiteralEqualityMode

Methods

AreBlankNodesEqual(IBlankNode, IBlankNode)

Determines whether two Blank Nodes are equal.

Declaration

public static bool AreBlankNodesEqual(IBlankNode a, IBlankNode b)

Parameters

Type	Name	Description
IBlankNode	a	First Blank Node.
IBlankNode	b	Second Blank Node.

Returns

Type	Description
System.Boolean

AreGraphLiteralsEqual(IGraphLiteralNode, IGraphLiteralNode)

Determines whether two Graph Literals are equal.

Declaration

public static bool AreGraphLiteralsEqual(IGraphLiteralNode a, IGraphLiteralNode b)

Parameters

Type	Name	Description
IGraphLiteralNode	a	First Blank Node.
IGraphLiteralNode	b	Second Blank Node.

Returns

Type	Description
System.Boolean

AreLiteralsEqual(ILiteralNode, ILiteralNode)

Determines whether two Literals are equal.

Declaration

public static bool AreLiteralsEqual(ILiteralNode a, ILiteralNode b)

Parameters

Type	Name	Description
ILiteralNode	a	First Literal.
ILiteralNode	b	Second Literal.

Returns

Type	Description
System.Boolean

AreRefNodesEqual(IRefNode, IRefNode)

Determines whether two reference nodes are equal.

Declaration

public static bool AreRefNodesEqual(IRefNode a, IRefNode b)

Parameters

Type	Name	Description
IRefNode	a	First reference node.
IRefNode	b	Second reference node.

Returns

Type	Description
System.Boolean

AreStringsEqual(string, string, StringComparison)

Determines whether two strings are equal.

Declaration

public static bool AreStringsEqual(string a, string b, StringComparison comparisonMode = StringComparison.Ordinal)

Parameters

Type	Name	Description
string	a
string	b
System.StringComparison	comparisonMode

Returns

Type	Description
System.Boolean	True if both a and b are null, or if a and b compare as equal under the given comparisonMode, false otherwise.

AreUrisEqual(Uri, Uri)

Determines whether two URIs are equal.

Declaration

public static bool AreUrisEqual(Uri a, Uri b)

Parameters

Type	Name	Description
System.Uri	a	First URI.
System.Uri	b	Second URI.

Returns

Type	Description
System.Boolean

Remarks

Unlike the Equals method provided by the System.Uri class by default this takes into account Fragment IDs which are essential for checking URI equality in RDF.

AreUrisEqual(IUriNode, IUriNode)

Determines whether two URIs are equal.

Declaration

public static bool AreUrisEqual(IUriNode a, IUriNode b)

Parameters

Type	Name	Description
IUriNode	a	First URI Node.
IUriNode	b	Second URI Node.

Returns

Type	Description
System.Boolean

AreVariablesEqual(IVariableNode, IVariableNode)

Determines whether two Variable Nodes are equal.

Declaration

public static bool AreVariablesEqual(IVariableNode a, IVariableNode b)

Parameters

Type	Name	Description
IVariableNode	a	First Variable Node.
IVariableNode	b	Second Variable Node.

Returns

Type	Description
System.Boolean
