Package org.neo4j.graphdb.traversal
Interface BranchCollisionDetector
public interface BranchCollisionDetector
In a bidirectional traversal there's one traversal from each start/end side and
they will probably meet somewhere in the middle and the full paths are formed.
This is where that detection and path generation takes place.

evaluate
Evaluate the givenbranch
coming from either the start side or the end side. Which side the branch represents is controlled by thedirection
argument,Direction.OUTGOING
means the start side andDirection.INCOMING
means the end side. Returns anIterable
of new uniquePath
s if this branch resulted in a collision with other previously registered branches, ornull
if this branch didn't result in any collision.- Parameters:
branch
- theTraversalBranch
to check for collision with other previously registered branches.direction
-Direction.OUTGOING
if this branch represents a branch from the start side of this bidirectional traversal, orDirection.INCOMING
for the end side.- Returns:
- new paths formed if this branch collided with other branches,
or
null
if no collision occurred.
