I haven't found in any javadoc or documentation what's the behavior of the BasicDBObject.append() with this code:

BasicDBObject query;
query.append("propertyName", value);
.... // more code, maybe a loop
query.append("propertyName", anotherValue);

Is this the JS equivalent of: query =

{propertyName: value, propertyName:anotherValue}

?

I know what does exactly happen in JS, but in Java I'm not sure.
