NotificationType

Canonical path: o6.server.NotificationType

Root shortcut: o6.NotificationType

NotificationType

Bases: IntEnum

open62541 Application Notification type encoding.

The high 32 bits are the category, the low 32 the sub-event — see deps/open62541/include/open62541/common.h. These are open62541's own values, not part of the OPC UA specification, so test_notification_type_matches_c_extension in tests/connections/test_server_notifications.py cross-checks every member against the compiled extension's own constants: an upstream encoding change fails that test loudly instead of silently diverging here.

Every member is listed, including the ones only a Server ever raises. A Client observes the LIFECYCLE_* and SERVICE_* members only.
