## org.neo4j.graphalgo
Interface PathFinder<P extends Path>

Type Parameters:
  `P` - the path type that the algorithm produces

    public interface PathFinder<P extends Path>

Interface of algorithms that finds paths in between two nodes.

Author:
  Tobias Ivarsson

Method Summary
`Iterable<P>` | `findAllPaths(Node start, Node end)` Tries to find all paths between `start` and `end` nodes.
`P` | `findSinglePath(Node start, Node end)` Tries to find a single path between `start` and `end` nodes.
`TraversalMetadata` | `metadata()`

Method Detail

### findSinglePath

    P findSinglePath(Node start,
                     Node end)

  Tries to find a single path between `start` and `end` nodes. If a path is found a `Path` is returned with that path information, else `null` is returned. If more than one path is found, the implementation can decide itself upon which of those to return.

  Parameters:
    `start` - the start `Node` which defines the start of the path.
    `end` - the end `Node` which defines the end of the path.
  Returns:
    a single `Path` between `start` and `end`, or `null` if no path was found.

### findAllPaths

    Iterable<P> findAllPaths(Node start,
                             Node end)

  Tries to find all paths between `start` and `end` nodes. A collection of `Path`s is returned with all the found paths. If no paths are found an empty collection is returned.

  Parameters:
    `start` - the start `Node` which defines the start of the path.
    `end` - the end `Node` which defines the end of the path.
  Returns:
    all `Path`s between `start` and `end`.

### metadata

    TraversalMetadata metadata()
