org.apache.sling.resourceresolver.impl.mapping.PathGenerator

public class PathGenerator
extends Object

Utility to generate all possible paths from segments (names)

This class expects to be supplied segments starting with the top-most ones (leaves) up until, but excluding, the root.

It generates all possible path combinations using a cartesian product that accummulates using a StringBuilder instead of a set, to prevent intermediate object creation.
