Syntax

public abstract class BaseRdfHandler : BaseHandler, ICommentRdfHandler, IRdfHandler, INodeFactory

Constructors

BaseRdfHandler()

Creates a new RDF Handler.

Declaration

protected BaseRdfHandler()

BaseRdfHandler(INodeFactory)

Creates a new RDF Handler using the given Node Factory.

Declaration

protected BaseRdfHandler(INodeFactory factory)

Parameters

Type	Name	Description
INodeFactory	factory	Node Factory.

Properties

AcceptsAll

Gets whether the Handler will accept all Triples i.e. it will never abort handling early.

Declaration

public abstract bool AcceptsAll { get; }

Property Value

Type	Description
bool

Methods

EndRdf(bool)

Ends the Handling of RDF.

Declaration

public void EndRdf(bool ok)

Parameters

Type	Name	Description
bool	ok	Whether the parsing completed without error.

EndRdfInternal(bool)

Optionally used by derived Handlers to do additional actions on ending RDF handling.

Declaration

protected virtual void EndRdfInternal(bool ok)

Parameters

Type	Name	Description
bool	ok	Whether the parsing completed without error.

HandleBaseUri(Uri)

Handles Base URI declarations.

Declaration

public bool HandleBaseUri(Uri baseUri)

Parameters

Type	Name	Description
Uri	baseUri	Base URI.

Returns

Type	Description
bool

HandleBaseUriInternal(Uri)

Optionally used by derived Handlers to do additional actions on handling Base URI declarations.

Declaration

protected virtual bool HandleBaseUriInternal(Uri baseUri)

Parameters

Type	Name	Description
Uri	baseUri	Base URI.

Returns

Type	Description
bool

HandleComment(string)

Handles Comments.

Declaration

public bool HandleComment(string text)

Parameters

Type	Name	Description
string	text	Comment text.

Returns

Type	Description
bool

HandleCommentInternal(string)

Optionally used by derived Handlers to do additional actions on handling Comments.

Declaration

protected virtual bool HandleCommentInternal(string text)

Parameters

Type	Name	Description
string	text	Comment text.

Returns

Type	Description
bool

HandleNamespace(string, Uri)

Handles Namespace declarations.

Declaration

public bool HandleNamespace(string prefix, Uri namespaceUri)

Parameters

Type	Name	Description
string	prefix	Prefix.
Uri	namespaceUri	Namespace URI.

Returns

Type	Description
bool

HandleNamespaceInternal(string, Uri)

Optionally used by derived Handlers to do additional actions on handling namespace declarations.

Declaration

protected virtual bool HandleNamespaceInternal(string prefix, Uri namespaceUri)

Parameters

Type	Name	Description
string	prefix	Prefix.
Uri	namespaceUri	Namespace URI.

Returns

Type	Description
bool

HandleQuad(Triple, IRefNode)

Handles Quads.

Declaration

public bool HandleQuad(Triple t, IRefNode graph)

Parameters

Type	Name	Description
Triple	t	Triple to handle.
IRefNode	graph	The name of the graph containing the triple.

Returns

Type	Description
bool

Exceptions

Type	Condition
RdfParseException	Raised if the handler is not currently in a state to handle quads.

HandleQuadInternal(Triple, IRefNode)

Must be overridden by derived handlers to take appropriate Quad handling action.

Declaration

protected abstract bool HandleQuadInternal(Triple t, IRefNode graph)

Parameters

Type	Name	Description
Triple	t	Triple.
IRefNode	graph	Name of the graph containing the triple.

Returns

Type	Description
bool

Remarks

Implementations that expect to only handle triples in the un-named graph SHOULD provide an implementation for this method that checks if graph is null and if so perform their standard triple handling processing.

HandleTriple(Triple)

Handles Triples.

Declaration

public bool HandleTriple(Triple t)

Parameters

Type	Name	Description
Triple	t	Triple.

Returns

Type	Description
bool

HandleTripleInternal(Triple)

Must be overridden by derived handlers to take appropriate Triple handling action.

Declaration

protected abstract bool HandleTripleInternal(Triple t)

Parameters

Type	Name	Description
Triple	t	Triple.

Returns

Type	Description
bool

StartRdf()

Starts the Handling of RDF.

Declaration

public void StartRdf()

StartRdfInternal()

Optionally used by derived Handlers to do additional actions on starting RDF handling.

Declaration

protected virtual void StartRdfInternal()
