comparison artifacts/src/main/java/org/dive4elements/river/artifacts/WaterLineArtifact.java @ 9425:3f49835a00c3
Extended CrossSectionFacet so it may fetch different data from within the artifact result.
Also allows to have acces to the potentially already computed artifact result via its normal computation cache.
