Asynchronously clears all values in the data store.

Returns
Type	Description
Task

DeleteAsync<T>(string)

public Task DeleteAsync<T>(string key)

Asynchronously deletes the given key. The type is provided here as well because the "real" saved key should contain type information as well, so the data store will be able to store the same key for different types.

Parameter
Name	Description
key	string The key to delete.

Returns
Type	Description
Task

Type Parameter
Name	Description
T	The type to delete from the data store.

GetAsync<T>(string)

public Task<T> GetAsync<T>(string key)

Asynchronously returns the stored value for the given key or null if not found. This implementation of IDataStore will always return a completed task with a result of null.

Type Parameter
Name	Description
T	The type to retrieve from the data store.

StoreAsync<T>(string, T)

public Task StoreAsync<T>(string key, T value)

Asynchronously stores the given value for the given key (replacing any existing value). This implementation of IDataStore does not store the value, and will not return it in future calls to GetAsync<T>(string).

Parameters
Name	Description
key	string The key.
value	T The value.

Returns
Type	Description
Task	A task that completes immediately.
