| 3 * src/main/java/de/intevation/flys/artifacts/model/WW.java: | |
| 4 Removed the createNormalized() method because it did not | |
| 5 solve all problems with the transformation of the W~W data we have. | |
| 6 | |
| 7 - We need to shift the values to be based in (0, 0). | |
| 8 - We need to linear transform the values if they are at gauges. | |
| 9 - Copying the data is memory expensive. | |
| 10 | |
| 11 Therefore there is now a new inner class ApplyFunctionIterator | |
| 12 that is able to transform the values in an iterator like manner. | |
| 13 The transform functions default to the identity. | |
| 14 | |
| 15 * src/main/java/de/intevation/flys/artifacts/math/Sub.java: New. | |
| 16 Simple function that subtract a scalar from the parameter. | |
| 17 | |
| 18 * src/main/java/de/intevation/flys/artifacts/model/W.java: Added | |
| 19 method minWs() to calulate the minimal W of the data. | |
| 20 | |
| 21 * src/main/java/de/intevation/flys/artifacts/model/NormalizedReferenceCurveFacet.java: | |
| 22 getData() returns a WW.ApplyFunctionIterator with identity transform. | |
| 23 | |
| 24 * src/main/java/de/intevation/flys/artifacts/model/ReferenceCurveFacet.java: | |
| 25 getData() returns a WW.ApplyFunctionIterator with a base shift to (0, 0). | |
