Brian,
Thank you for explaining that and suggesting to extend HashMap. I did exactly
that. Here is what it looks like:
class DocMap extends HashMap<String, Object> {
/**
* Generated id
*/
private static final long serialVersionUID = 5807773481499313384L;
@RiakIndex(name="status") private String status;
public String getStatus() {
return status;
}
public void setStatus(String status) {
this.status = status;
}
}
I am about to try it, but I first need to make a few more changes in the code
to adapt this new object. In the meantime, would you say that this looks
correct and that it would be able to effectively write a status field to a
secondary index if I were to use "setStatus"?
Thanks,
Jeff
