Namespace:  VDS.RDF.Parsing
Assembly:  dotNetRDF (in dotNetRDF.dll) Version:
Syntax
public static void Load(
	IGraph g,
	Uri u,
	GraphCallback callback,
	Object state
)

Parameters

g
Type: VDS.RDFIGraph
Graph to assert triple in.
u
Type: SystemUri
URI to load from.
callback
Type: VDS.RDFGraphCallback
Callback to invoke when the operation completes.
state
Type: SystemObject
State to pass to the callback.
Remarks

Will attempt to autodetect the format of the RDF based on the Content-Type header of the HTTP response.

In the event that the URI is a File URI the FileLoader will be used instead. If the URI is a Data URI then the DataUriLoader will be used instead.

Note: UriLoader will assign the Graph the source URI as it's Base URI unless the Graph already has a Base URI or is non-empty prior to attempting parsing. Note that any Base URI specified in the RDF contained in the file will override this initial Base URI. In some cases this may lead to invalid RDF being accepted and generating strange relative URIs, if you encounter this either set a Base URI prior to calling this method or create an instance of the relevant parser and invoke it directly.

If the loading completes normally the callback will be invoked normally, if an error occurs it will be invoked and passed an instance of AsyncError as the state which contains details of the error and the original state.
