Examples of org.jboss.dna.graph.property.PathFactory

org.jboss.dna.graph.property.PathFactory
A factory for creating {@link Path paths}. This interface extends the {@link ValueFactory} generic interface and adds specificmethods for creating paths (and relative paths) from a series of names, segments, or combinations.
