Method Detail

addPath

public void addPath(Path<Feature,java.lang.String> path)
             throws FeatureTypeMismatchException,
                    GraphException

Throws:

FeatureTypeMismatchException

GraphException

reorient

public void reorient(FeatureHierarchy hierarchy)
              throws FeatureTypeMismatchException,
                     GraphException

Reorients this graph to match a given FeatureHierarchy. If the FeatureHierarchy does not define positions for all of the Features present in this graph, they will be assigned on a first-come, first-served basis.

Parameters:

hierarchy - the new FeatureHierarchy this graph should take on.

Throws:

FeatureTypeMismatchException

GraphException

evaluateQuery

public java.util.List<Path<Feature,java.lang.String>> evaluateQuery(Query query)

evaluateQuery
