After the GIS data is retrieved from Database, how to add offset to them before
publishing map.
For example, moving all point or line to north 100 meters.
Should I modify the following code ?
final Integer startIndex = request.getStartIndex();
if (startIndex != null) {
QueryCapabilities queryCapabilities =
source.getQueryCapabilities();
if (queryCapabilities.isOffsetSupported()) {
// fsource is required to support
// SortBy.NATURAL_ORDER so we don't bother checking
definitionQuery.setStartIndex(startIndex);
} else {
// source = new PagingFeatureSource(source,
// request.getStartIndex(), limit);
throw new ServiceException("startIndex is not supported
for the "
+ mapLayerInfo.getName() + " layer");
}
}
