Question

I’m wondering what would be the best way to set a NULL (or NIL) value to a pointer in makumba using the API?

I’ve tried something like this:

Dictionary<String,Object> emptyActivity = new Hashtable<String, Object>();
emptyActivity.put("activity", null);
db.update((Pointer)pointer, emptyActivity);

However I can’t put null to the dictionary so I’m not sure what to do here. Is there a java object representing a null value?

Answer 1

Instead of null, you should use an instance of Makumba’s NullObject (http://www.makumba.org/api/org/makumba/NullObject.html).

For pointers, you can reuse the constant Pointer.Null (http://www.makumba.org/api/org/makumba/Pointer.html#Null)

So, your code is then

emptyActivity.put("activity", Pointer.Null);
