Make URIParser code more readable - Part 2
- declare variables closer to where they are used - move more validation into the validatePath method - increment the global index variable i in fewer places Issue-ID: AAI-3656 Signed-off-by: Fiete Ostkamp <Fiete.Ostkamp@telekom.de> Change-Id: I64380b84370a362113bf64c4edff3d389ffb290e
