Constructors

BaseBlankNode(string)

Internal Only constructor for Blank Nodes.

Declaration

protected BaseBlankNode(string nodeId)

Parameters

Type	Name	Description
string	nodeId	Custom Node ID to use.

BaseBlankNode(INodeFactory)

Internal Only constructor for Blank Nodes.

Declaration

protected BaseBlankNode(INodeFactory factory)

Parameters

Type	Name	Description
INodeFactory	factory	Node Factory from which to obtain a Node ID.

Properties

EffectiveType

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

Declaration

public string EffectiveType { get; }

Property Value

Type	Description
string

HasAutoAssignedID

Indicates whether this Blank Node had its ID assigned for it by the Graph.

Declaration

public bool HasAutoAssignedID { get; }

Property Value

Type	Description
bool

InternalID

Returns the Internal Blank Node ID this Node has in the Graph.

Declaration

public string InternalID { get; }

Property Value

Type	Description
string

Remarks

Usually automatically assigned and of the form autosXXX where XXX is some number. If an RDF document contains a Blank Node ID of this form that clashes with an existing auto-assigned ID it will be automatically remapped by the Graph using the BlankNodeMapper when it is created.

NumericType

Gets the Numeric Type of the Node.

Declaration

public SparqlNumericType NumericType { get; }

Property Value

Type	Description
SparqlNumericType
