Dummy state store implementation that doesn’t do anything.
Implements: IStateStore
Description
It can be used in testing or in situations when state management is not required but shall be disabled.
Instance methods
delete
Deletes a state from the store by its key.
Future<T?> delete<T>(IContext? context, String key)
- context: IContext - (optional) a context to trace execution through a call chain.
- key: String - a unique value key.
- return: Future<T?> - removed item
load
Loads state from the store using its key. If value is missing in the store it returns null.
Future<T?> load<T>(IContext? context, String key)
- context: IContext - (optional) a context to trace execution through a call chain.
- key: String - a unique state key.
- return: Future<T?> - the state value or
nullif value wasn’t found.
loadBulk
Loads an array of states from the store using their keys.
Future<List<StateValue<T>>> loadBulk<T>(IContext? context, List<String> keys)
- context: IContext - (optional) a context to trace execution through a call chain.
- keys: List<String> - unique state keys.
- returns: Future<List<StateValue<T>>> - an array with state values and their corresponding keys.
save
Saves state into the store.
Future<T> save<T>(IContext? context, String key, value)
- context: IContext - (optional) a context to trace execution through a call chain.
- key: String - a unique state key.
- value: dynamic - a state value.
- returns: Future<T> - execution duration in milliseconds.
