Interface PathSearch<P>

Type Parameters:
P -
All Known Implementing Classes:
PathSearchBase, PathSearchSparqlBase
public interface PathSearch<P>
A PathSearch represents a search of paths under given parameters. This interface provides methods to limit the number of results and their lengths. Implementations may e.g. forward these parameters to the backing core algorithm - or they may simply post-process a stream of paths by these conditions.
