Method Detail

next

public TraversalBranch next()

Description copied from interface: BranchSelector

Decides the next position ("where to go from here") from the current position, based on the rules. Since TraversalBranch has the TraversalBranch.node() of the position and the TraversalBranch.relationship() to how it got there as well as TraversalBranch.position(), decisions can be based on the current expansion source and the given rules.

Specified by:

next in interface BranchSelector

Returns:

the next position based on the current position and the rules of the traversal.
