annotate flys-backend/src/main/java/de/intevation/flys/backend/SpatialInfo.java @ 5092:ed237d6e8e27 dami

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Add HWSLinesInfo and point the old doLinesInfo method on that. doLinesInfo can be removed once HWS usage is properly implemented
