import 'package:jaguar_serializer/serializer.dart';

main() async {
  final repo = new JsonRepo();
  final cache = new InMemoryCache(repo);

  // Upsert
  cache.upsert('one', 1, new Duration(seconds: 5));
  print(cache.read('one'));

  // Replace
  cache.replace('one', 2, new Duration(seconds: 5));
  print(cache.read('one'));

  // Expire
  await new Future.delayed(new Duration(seconds: 5));

  try {
    cache.read('one');
  } catch(e) {
    print('Success! $e');
  }

  cache.upsert('one', 1.0, new Duration(seconds: 5));
  cache.upsert('two', 2.0, new Duration(seconds: 5));

  print(cache.readMany(['one', 'two']));
}

Operations

Upsert

Sets the given key/value in the cache, overwriting any existing value associated with that key.

  cache.upsert('one', 1, new Duration(seconds: 5));
  print(cache.read('one'));

Read

Get the content associated with the given key

  print(cache.read('one'));

Read many

Get the content associated multiple keys at once.

  cache.upsert('one', 1.0, new Duration(seconds: 5));
  cache.upsert('two', 2.0, new Duration(seconds: 5));

  print(cache.readMany(['one', 'two']));

Replace

Set the given key/value in the cache ONLY IF the key already exists.

  cache.replace('one', 2, new Duration(seconds: 5));
  print(cache.read('one'));
