onGetValue abstract method

Future<T> onGetValue(
  1. String k
)

Abstract method to be implemented by subclasses for asynchronously retrieving the value associated with a key.

Returns a Future<T> representing the fetched value. Called internally by getValue; should handle storage-specific logic, such as nested map traversal in ArcaneFieldMapProvider or API calls in ArcaneFieldDirectProvider. No side effects expected.

Implementation

Future<T> onGetValue(String k);
