Public Attributes Documentation

variable gid

16-byte subscription GID.

uint8_t AstuteDDSSubscription::gid[16];

---

variable listener_mtx

std::mutex AstuteDDSSubscription::listener_mtx;

Protects every on_*_cb / on_*_ud pair below (including the "new message" pair); see AstuteDDSPublisher::listener_mtx for why a single mutex + full-struct rebuild is required.

---

variable on_new_message_cb

rmw_event_callback_t AstuteDDSSubscription::on_new_message_cb;

User callback registered via rmw_subscription_set_on_new_message_callback; null when no callback is registered.

---

variable on_new_message_user_data

Opaque pointer passed back verbatim to on_new_message_cb .

const void* AstuteDDSSubscription::on_new_message_user_data;
