Method Detail

connect

public static RDFConnection connect(String destination)

Create a connection to a remote location by URL. This is the URL for the dataset. This call assumes the names of services as:

• SPARQL Query endpoint : "sparql"
• SPARQL Update endpoint : "update"
• SPARQL Graph Store Protocol : "data"

These are the default names in Fuseki Other names can be specified using connect(String, String, String, String)

Parameters:

destination -

Returns:

RDFConnection

connect(String, String, String, String)

connect

public static RDFConnection connect(String queryServiceEndpoint,
                                    String updateServiceEndpoint,
                                    String graphStoreProtocolEndpoint)

Create a connection specifying the URLs of the service.

Parameters:

queryServiceEndpoint -

updateServiceEndpoint -

graphStoreProtocolEndpoint -

Returns:

RDFConnection

connect

public static RDFConnection connect(String datasetURL,
                                    String queryServiceEndpoint,
                                    String updateServiceEndpoint,
                                    String graphStoreProtocolEndpoint)

Create a connection to a remote location by URL. This is the URL for the dataset. Each service is then specified by a URL which is relative to the datasetURL.

Parameters:

datasetURL -

queryServiceEndpoint -

updateServiceEndpoint -

graphStoreProtocolEndpoint -

Returns:

RDFConnection

connectPW

public static RDFConnection connectPW(String URL,
                                      String user,
                                      String password)

Make a remote RDFConnection to the URL, with user and password for the client access using basic auth. Use with care. Basic auth over plain HTTP reveals the password on the network.

Parameters:

URL -

user -

password -

Returns:

RDFConnection

connect

public static RDFConnection connect(Dataset dataset)

Connect to a local (same JVM) dataset. The default isolation is NONE. See connect(Dataset, Isolation) to select an isolation mode.

Parameters:

dataset -

Returns:

RDFConnection

See Also:

RDFConnectionLocal

connect

public static RDFConnection connect(Dataset dataset,
                                    Isolation isolation)

Connect to a local (same JVM) dataset.

Multiple levels of Isolation are provided, The default COPY level makes a local RDFConnection behave like a remote conenction. See the documentation for more details.

• COPY – Models and Datasets are copied. This is most like a remote connection.
• READONLY – Read-only wrappers are added but changes to the underlying model or dataset will be seen.
• NONE (default) – Changes to the returned Models or Datasets act on the original object.

Parameters:

dataset -

isolation -

Returns:

RDFConnection

connectFuseki

public static RDFConnectionFuseki connectFuseki(String destination)

Create a connection to a remote Fuseki server by URL. This is the URL for the dataset.

A RDFConnectionFuseki is an RDFConnection that:

• provides round-trip of blank nodes between this application and the server
• uses the more efficient RDF Thrift binary format.

This factory call assumes the names of services as:

• SPARQL Query endpoint : "sparql"
• SPARQL Update endpoint : "update"
• SPARQL Graph Store Protocol : "data"

These are the default names in Fuseki Other names can be specified using connectFuseki(String, String, String, String).

Parameters:

destination -

Returns:

RDFConnectionFuseki

connectFuseki

public static RDFConnectionFuseki connectFuseki(String datasetURL,
                                                String queryServiceEndpoint,
                                                String updateServiceEndpoint,
                                                String graphStoreProtocolEndpoint)

Create a connection to a remote Fuseki server by URL. This is the URL for the dataset. Each service is then specified by a URL which is relative to the datasetURL.

Parameters:

datasetURL -

queryServiceEndpoint -

updateServiceEndpoint -

graphStoreProtocolEndpoint -

Returns:

RDFConnectionFuseki
