Constructor Detail

UpdateProcessRemoteBase

public UpdateProcessRemoteBase(UpdateRequest request,
                       String endpoint,
                       Context context)

Creates a new remote update processor

Parameters:

request - Update request

endpoint - Update endpoint

context - Context

Method Detail

getGraphStore

public GraphStore getGraphStore()

Description copied from interface: UpdateProcessor

The dataset against which the query will execute. May be null, implying the there isn't a local GraphStore target for this UpdateProcessor.

Specified by:

getGraphStore in interface UpdateProcessor

getEndpoint

public String getEndpoint()

Gets the endpoint

Returns:

Endpoint URI

getQueryString

public String getQueryString()

Gets the generated query string portion of the endpoint URL if applicable

Generated string will not include leading ? so that consuming code can decide whether to add this themselves since the generated query string may be being used in addition to an existing query string.

Returns:

Generated query string

getParams

public Params getParams()

Gets the parameters for the execution

Returns:

Parameters

getUpdateRequest

public UpdateRequest getUpdateRequest()

Gets the update request

Returns:

Update request

addDefaultGraph

public void addDefaultGraph(String defaultGraph)

Adds a default graph

Parameters:

defaultGraph - Default Graph URI

addNamedGraph

public void addNamedGraph(String namedGraph)

Adds a named graph

Parameters:

namedGraph - Named Graph URi

setDefaultGraphs

public void setDefaultGraphs(List<String> defaultGraphs)

Sets the default graphs

Parameters:

defaultGraphs - Default Graphs

setNamedGraphs

public void setNamedGraphs(List<String> namedGraphs)

Sets the named graphs

Parameters:

namedGraphs - Named Graphs

setHttpContext

public void setHttpContext(org.apache.http.protocol.HttpContext httpContext)

Convenience method to set the HttpContext

Parameters:

httpContext - HTTP Context

getHttpContext

public org.apache.http.protocol.HttpContext getHttpContext()

Convenience method to get the HttpContext

Returns:

HttpContext

getContext

public Context getContext()

Description copied from interface: UpdateProcessor

The properties associated with a query execution - implementation specific parameters This includes Java objects (so it is not an RDF graph). Keys should be URIs as strings. May be null (this implementation does not provide any configuration).

Specified by:

getContext in interface UpdateProcessor

setAuthentication

public void setAuthentication(String username,
                     char[] password)

Sets authentication credentials for remote updates

Parameters:

username - Username

password - Password

isUsingAuthentication

public boolean isUsingAuthentication()

Gets whether any authentication credentials have been set

Returns:

True if credentials have been set, false otherwise
