Examples of org.bson.BasicBSONObject

org.bson.BasicBSONObject
A simple implementation of DBObject. A DBObject can be created as follows, using this class:
```
 DBObject obj = new BasicBSONObject(); obj.put( "foo", "bar" ); 
```

        return response;


    }


    private void putLastError(Channel channel, MongoServerException ex) {
        BSONObject error = new BasicBSONObject();
        if (ex instanceof MongoServerError) {
            MongoServerError err = (MongoServerError) ex;
            error.put("err", err.getMessage());
            error.put("code", Integer.valueOf(err.getCode()));
        } else {
            error.put("err", ex.getMessage());
        }
        // TODO: https://github.com/netty/netty/issues/1810
        // also note:
        // http://stackoverflow.com/questions/17690094/channel-id-has-been-removed-in-netty4-0-final-version-how-can-i-solve
        error.put("connectionId", Integer.valueOf(channel.hashCode()));
        putLastResult(channel, error);
