SessionPresenceStore class abstract interface

Registry of live sessions: a running agent process registers on start, touches on every heartbeat tick, unregisters on exit. Readers (SessionPresenceStore.list) see only fresh entries — a crashed process is covered by staleness, not by cleanup.

Methods

list() → Future<Map<String, SessionPresence>>

noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
register(String sessionId, {int? pid, String? host}) → Future<void>
Announces a live process owning sessionId. Also refreshes touchedAt (a register is a touch).
toString() → String
A string representation of this object.
inherited
touch(String sessionId) → Future<void>
Refreshes the heartbeat for sessionId (no-op when not registered).
unregister(String sessionId) → Future<void>
Removes the heartbeat for sessionId (clean exit path).
