populate

public static G populate(GDataConf dataConf,
         G g)
                  throws SLIB_Exception

Populate a given graph considering a configuration.

Parameters:

dataConf - the object defining the configuration of the data to load

g - the graph to populate with the data

Returns:

the graph which have been populated. The treatment is performed in place, i.e. no extra graph is created and the reference to the graph returned will be the same as the one passed in parameter.

Throws:

SLIB_Exception - if an error is encountered during loading.

createGraph

public static G createGraph(org.openrdf.model.URI uri)

Create a graph and register it.

Parameters:

uri - the URI of the graph

Returns:

the created graph.

load

public static G load(GraphConf graphConf)
              throws SLIB_Exception

Build the graph considering the given configuration.

Parameters:

graphConf - the graph configuration

Returns:

the graph which as been build form the configuration

Throws:

SLIB_Exception

load

public static G load(GraphConf graphConf,
     G g)
              throws SLIB_Exception

Impact the given graph considering the given configuration. The graph will be populated by the data and actions will be performed on it if any exist.

Parameters:

graphConf - the graph configuration

g - the graph

Returns:

the graph which as been build form the configuration

Throws:

SLIB_Exception

load

public static void load(Collection<GraphConf> graphConfs)
                 throws SLIB_Exception

Load the collection of configurations.

Parameters:

graphConfs - the collection of configurations

Throws:

SLIB_Exception

supportFormat

public static boolean supportFormat(String format)

Check if the generic loader support the given format.

Parameters:

format - the format

Returns:

true if the format is supported.

getSupportedFormat

public static GFormat[] getSupportedFormat()

Access to the set of supported format.

Returns:

the list of format which are supported by the generic loader.
