Hi all,
Is using NativeLong in structures supported? I have a structure:
public class CFRange extends Structure implements Structure.ByValue {
public CFIndex location;
public CFIndex length;
public CFRange() {
}
public CFRange(final CFIndex location, final CFIndex length) {
this.location = location;
this.length = length;
}
public CFIndex getLength() {
return length;
}
public CFIndex getLocation() {
return location;
}
}
Where CFIndex is
public class CFIndex extends NativeLong {
private static final long serialVersionUID = 0;
}
But I'm getting this error:
Caused by: java.lang.IllegalArgumentException: Unsupported structure

Is it really true that NativeLong types don't work in Structures? If
so, how to handle 32/64 bit Structures.
Could I add this to Structure myself reasonably easily or are there
deep and evil reasons why it is hard?
