FMTCBackendInternalThreadSafe class abstract interface

An abstract interface that FMTC will use to communicate with a storage 'backend' (usually one root), from an existing bulk downloading thread

Should implement methods that operate in the same thread. Must be sendable between isolates when uninitialised, because it will be operated in another thread. Must be suitable for simultaneous initialiseation across multiple threads.

Should be set-up ready for intialisation, and set in the FMTCBackendAccessThreadSafe, from the initialisation of FMTCBackendInternal. See documentation on that class for more information.

Methods with a doc template in the doc string are for 'direct' public invocation.

See FMTCBackend for more information.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

readTile({required String url, String? storeName}) → FutureOr<BackendTile?>

toString() → String

A string representation of this object.

inherited

uninitialise() → FutureOr<void>
