empty<K, V> static method
Returns an empty IMapOfSets, with the given configuration. If a configuration is not provided, it will use the default configuration.
Note: If you want to create an empty immutable collection of the same type and same configuration as a source collection, simply call clear in the source collection.
Implementation
static IMapOfSets<K, V> empty<K, V>([ConfigMapOfSets? config]) {
config ??= defaultConfig;
return IMapOfSets<K, V>._unsafe(IMap.empty(config.asConfigMap), config);
}
