You are looking at old code. The current code base evaluates the axis order
this way:
private boolean axisFlipped(String srsName) {
Version version = new Version(wms.getCapabilities().getVersion());
if(version.compareTo(new Version("1.3.0")) < 0) {
// aah, sheer simplicity
return false;
} else {
// gah, hell gates breaking loose
if(srsName.startsWith("EPSG:")) {
try {
String epsgNative =
"urn:x-ogc:def:crs:EPSG:".concat(srsName.substring(5));
return CRS.getAxisOrder(CRS.decode(epsgNative)) ==
AxisOrder.NORTH_EAST;
} catch(Exception e) {
LOGGER.log(Level.WARNING, "Failed to determine axis
order for "
+ srsName + ", assuming east/north", e);
return false;
}
} else {
// CRS or AUTO, none of them is flipped so far
return false;
}
}
}
