1 class JPQEntry

Stores priority queue informations for shortest path resp. network distance
computation within JNetAlgebra.

It consist of three junction identifiers, one for the
junction at the start of the shortest path, one for the junction currently
reached and one for the junction before current junction, two double values
one for the priority value and one for the network distance of the current
junction from the start of the shortest path, the section identifier of the
section between current junction and before junction, and the route interval
describing this section.
