Examples of com.mongodb.CommandResult

com.mongodb.CommandResult
A simple wrapper for the result of getLastError() calls and other commands

            DBCollection collection = db.getCollection("useradmin");
            // we always get a collection back, regardless if there is an actual MongoDB listening, hence we should do
            // some actual calls that cause a connection to MongoDB to be created...
            collection.remove(new BasicDBObject(), WriteConcern.SAFE);


            CommandResult lastError = db.getLastError();


            return (lastError.getException() == null && collection.getCount() == 0L);
        }
        catch (Exception e)
        {
            // Ignore; apparently, we failed to connect to MongoDB...
        }
