Methods

	Name	Description
	ApplyRequestOptions	Helper method which applies standard request options to the request, these currently include proxy settings and HTTP timeout. (Inherited from BaseHttpConnector.)
	ClearProxy	Clears any in-use credentials so subsequent requests will not use a proxy server. (Inherited from BaseHttpConnector.)
	ClearProxyCredentials	Clears the in-use proxy credentials so subsequent requests still use the proxy server but without credentials. (Inherited from BaseHttpConnector.)
	DeleteGraph(String)	Deletes a Graph from the store.
	DeleteGraph(Uri)	Deletes a Graph from the store.
	DeleteGraph(Uri, AsyncStorageCallback, Object)	Deletes a Graph from the Store. (Inherited from BaseAsyncHttpConnector.)
	DeleteGraph(String, AsyncStorageCallback, Object)	Deletes a Graph from the store asynchronously. (Overrides BaseAsyncHttpConnectorDeleteGraph(String, AsyncStorageCallback, Object).)
	DeleteGraphAsync	Helper method for doing async delete operations, callers just need to provide an appropriately prepared HTTP request. (Inherited from BaseAsyncHttpConnector.)
	Dispose	Disposes of the Connection. (Overrides BaseAsyncHttpConnectorDispose.)
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	GetHashCode	Serves as the default hash function. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	HasGraph(String)	Sends a HEAD Command to the Protocol Server to determine whether a given Graph exists.
	HasGraph(Uri)	Sends a HEAD Command to the Protocol Server to determine whether a given Graph exists.
	ListGraphs	Throws an exception as listing graphs in a SPARQL Graph Store HTTP Protocol does not support listing graphs.
	ListGraphs(AsyncStorageCallback, Object)	Lists the Graphs in the Store asynchronously. (Overrides BaseAsyncHttpConnectorListGraphs(AsyncStorageCallback, Object).)
	LoadGraph(IGraph, String)	Loads a Graph from the Protocol Server.
	LoadGraph(IGraph, Uri)	Loads a Graph from the Protocol Server.
	LoadGraph(IRdfHandler, String)	Loads a Graph from the Protocol Server.
	LoadGraph(IRdfHandler, Uri)	Loads a Graph from the Protocol Server.
	LoadGraph(IGraph, Uri, AsyncStorageCallback, Object)	Loads a Graph from the Store asynchronously. (Inherited from BaseAsyncHttpConnector.)
	LoadGraph(IGraph, String, AsyncStorageCallback, Object)	Loads a Graph from the Protocol Server. (Overrides BaseAsyncHttpConnectorLoadGraph(IGraph, String, AsyncStorageCallback, Object).)
	LoadGraph(IRdfHandler, Uri, AsyncStorageCallback, Object)	Loads a Graph from the Store asynchronously. (Inherited from BaseAsyncHttpConnector.)
	LoadGraph(IRdfHandler, String, AsyncStorageCallback, Object)	Loads a Graph from the Protocol Server. (Overrides BaseAsyncHttpConnectorLoadGraph(IRdfHandler, String, AsyncStorageCallback, Object).)
	LoadGraphAsync	Helper method for doing async load operations, callers just need to provide an appropriately prepared HTTP request. (Inherited from BaseAsyncHttpConnector.)
	MakeRequestSequence	Helper method for doing async operations where a sequence of HTTP requests must be run. (Inherited from BaseAsyncHttpConnector.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	SaveGraph(IGraph)	Saves a Graph to the Protocol Server.
	SaveGraph(IGraph, AsyncStorageCallback, Object)	Saves a Graph to the Protocol Server. (Overrides BaseAsyncHttpConnectorSaveGraph(IGraph, AsyncStorageCallback, Object).)
	SaveGraphAsync	Helper method for doing async save operations, callers just need to provide an appropriately perpared HTTP requests and a RDF writer which will be used to write the data to the request body. (Inherited from BaseAsyncHttpConnector.)
	SerializeConfiguration	Serializes the connection's configuration.
	SerializeStandardConfig	Helper method which adds standard configuration information (proxy and timeout settings) to serialized configuration. (Inherited from BaseHttpConnector.)
	SetCredentials	(Inherited from BaseHttpConnector.)
	SetProxy(String)	Sets a Proxy Server to be used. (Inherited from BaseHttpConnector.)

Remarks

The SPARQL Graph Store HTTP Protocol is defined as part of SPARQL 1.1 and is currently a working draft so implementations are not guaranteed to be fully compliant with the draft and the protocol may change in the future.

Note: While this connector supports the update of a Graph the Graph Store HTTP Protocol only allows for the addition of data to an existing Graph and not the removal of data, therefore any calls to UpdateGraph() that would require the removal of Triple(s) will result in an error.
