transformCoordinates method
Transforms a {@link CoordinateSequence}. This method should always return a valid coordinate list for the desired result type. (E.g. a coordinate list for a LineString must have 0 or at least 2 points). If this is not possible, return an empty sequence - this will be pruned out.
@param coords the coordinates to transform @param parent the parent geometry @return the transformed coordinates
Implementation
CoordinateSequence transformCoordinates(
CoordinateSequence coords, Geometry parent) {
// for linear components (including rings), simplify the linestring
if (parent is LineString) {
TaggedLineString? taggedLine = linestringMap[parent];
if (taggedLine != null) {
return createCoordinateSequence(taggedLine.getResultCoordinates());
}
}
// for anything else (e.g. points) just copy the coordinates
return super.transformCoordinates(coords, parent);
}
