annotate flys-artifacts/src/main/java/de/intevation/flys/exports/fixings/FixChartGenerator.java @ 4446:05a54b4d579d

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Remove AbstractFixGenerator and use new KMIndexProcessor instead Don't use same base class for minfo and fixings artifacts. Instead use the new KMIndexProcessor to generate the same output for the same data types and facets.
