Examples of evaluatePath()

fr.inria.jfresnel.fsl.sesame.FSLSesameEvaluator.evaluatePath()
Evaluate a path expression on the repository set by setRepository(Repository r).
The initial set of nodes/arcs (i.e., the set of nodes or arcs that are going to be considered as potential starting points for matching paths) is:
1) all resource nodes in the graph if firstStepType = NODE_STEP and the first location step does not test for a literal node (i.e. it is not "text()");
2) all literal nodes in the graph if firstStepType = NODE_STEP and the first location step tests for a literal node (i.e. it is "text()");
3) all property arcs in the graph if firstStepType = ARC_STEP @param p the FSL path expression (use FSLPath.pathFactory() to build it from its String representation) @return a Vector containing Vectors that represent sequences of nodes/arcs that are instances of actual paths in the graph that match the FSL expression. These vectors are made of Sesame org.openrdf.model.Resource or org.openrdf.model.Literal objects for node steps and org.openrdf.model.Statement objects for arc steps. Naturally, one every two steps is a Resource or a Literal, the other being a Statement. @see #evaluatePath(FSLPath p,HashMap startSet) Modified to accept inferred statements and to prevent selection over the whole database
org.apache.marmotta.client.clients.LDPathClient.evaluatePath()
Evaluate the path query passed as second argument, starting at the resource with the uri given as first argument. Returns a List of RDFNode objects. @param uri the uri of the resource where to start the path evaluation @param path the path to evaluate @return a list of RDFNodes representing the result of the path evaluation as returned by the server @throws MarmottaClientException @throws IOException
