comparison flys-backend/src/main/java/de/intevation/flys/model/RiverAxis.java @ 2375:61cb16549eb1
Modified the signature of RiverAxis.getRiverAxis() which now returns a list of RiverAxis objects instead of a single instance.

| 23 * There is a modeling problem with the RiverAxis. The initial idea was, that a | |
| 24 * river can have a riveraxis that consist of exact one geometry. Now, it has | |
| 25 * turned out, that a single geometry is not enough for a riveraxis (arm of a | |
| 26 * river, inflows, ...). As workaround, we now expect, that a river can just | |
| 27 * have a single riveraxis. | |
