Method Detail

buildTriplet

public static E buildTriplet(Object s,
             Object p,
             Object o)

Build a triplet of URIs considering the given subject-predicate-object objects (for instance, specified as URI or String objects). The URIs which compose the triplet can be specified as URI objects, as String objects or using any objects for which the toString method returns a valid URI.

Parameters:

s - the URI which refers to the subject of the triplet (possibly as a String)

p - the URI which refers to the predicate of the triplet (possibly as a String)

o - the URI which refers to the object of the triplet (possibly as a String)

Returns:

the Edge

buildTriplet

public static E buildTriplet(String s,
             String p,
             String o)

Build a triplet of URIs considering the given subject-predicate-object objects as String objects.

Parameters:

s - the URI which refers to the subject of the triplet

p - the URI which refers to the predicate of the triplet

o - the URI which refers to the object of the triplet

Returns:

the Edge

buildTriplet

public static E buildTriplet(URIFactory f,
             String s,
             String p,
             String o)

Build a triplet of URIs considering the given subject-predicate-object objects as String objects.

Parameters:

f - the factory which will be used to generate the URIs

s - the URI which refers to the subject of the triplet

p - the URI which refers to the predicate of the triplet

o - the URI which refers to the object of the triplet

Returns:

the Edge

buildTriplet

public static E buildTriplet(URIFactory f,
             Object s,
             Object p,
             Object o)

Build a triplet of URIs considering the given subject-predicate-object objects (for instance, specified as URI or String objects). The URIs which compose the triplet can be specified as URI objects, as String objects or using any objects for which the toString method returns a valid URI.

Parameters:

f - the factory used to build the URIs if necessary

s - the URI which refers to the subject of the triplet (possibly as a String)

p - the URI which refers to the predicate of the triplet (possibly as a String)

o - the URI which refers to the object of the triplet (possibly as a String)

Returns:

the Edge

addTriplet

public static void addTriplet(G graph,
              Object s,
              Object p,
              Object o)

Add a triplet to the given graph. The URIs which compose the triplet can be specified as URI objects, as String objects or using any objects for which the toString method returns a valid URI.

Parameters:

graph -

s - the URI which refers to the subject of the triplet (possibly as a String)

p - the URI which refers to the predicate of the triplet (possibly as a String)

o - the URI which refers to the object of the triplet (possibly as a String)

addTriplet

public static void addTriplet(G graph,
              String s,
              String p,
              String o)

Add a triplet to the given graph. The URIs which compose the triplet are specified as String objects.

Parameters:

graph -

s - the URI which refers to the subject of the triplet

p - the URI which refers to the predicate of the triplet

o - the URI which refers to the object of the triplet

loadStatements

public static void loadStatements(G g,
                  org.openrdf.repository.RepositoryResult<org.openrdf.model.Statement> statements)
                           throws org.openrdf.repository.RepositoryException

Load the set of statements only composed of URIs into the given graph.

Parameters:

g - the graph in which the statements must be loaded

statements - the set of statements from which the filter is applied

Throws:

org.openrdf.repository.RepositoryException
