I have an field in database that is null When I retrieve it in a cursor it is null. I can tell that from the
cursor.isNull(1) is true So when I do cursor.getLong(1) it should throw an exception according to the documentation. but it actually retrieves 0 without and exception. any ideas why?
If you take a look at the implementation of the method getLong()
in MatrixCursor , you can see the following code:
@Override
public long getLong(int column) {
Object value = get(column);
if (value == null) return 0;
if (value instanceof Number) return ((Number) value).longValue();
return Long.parseLong(value.toString());
}
If the value is null, then 0 is returned.
