Member Function Documentation

best_available()

constexpr QoS rclcpp::detail::qos_table::best_available ( )

inlinestaticconstexpr

rmw_qos_profile_best_available (Iron+) — KEEP_LAST(10), and every policy that can be best-available set so: reliability, durability, liveliness, deadline, liveliness lease (issue 1973).

clock()

constexpr QoS rclcpp::detail::qos_table::clock ( )

inlinestaticconstexpr

rclcpp::ClockQoS — KEEP_LAST(1), BEST_EFFORT, VOLATILE.

Upstream builds it from rmw_qos_profile_sensor_data with KeepLast(1) (rclcpp/qos.hpp:371-377), which is why the depth differs from sensor_data()'s 5 and the reliability does not.

default_profile()

constexpr QoS rclcpp::detail::qos_table::default_profile ( )

inlinestaticconstexpr

rmw_qos_profile_default — KEEP_LAST(10), RELIABLE, VOLATILE.

Spelled by QoS's default constructor's member-init list, which IS this profile; naming it here would be the second copy this table removes.

parameter_events()

constexpr QoS rclcpp::detail::qos_table::parameter_events ( )

inlinestaticconstexpr

rmw_qos_profile_parameter_events — KEEP_LAST(1000), RELIABLE, VOLATILE.

Same shape as parameters() upstream and still its own row: they are two upstream constants that happen to agree today, and collapsing them would make a future divergence invisible.

parameters()

constexpr QoS rclcpp::detail::qos_table::parameters ( )

inlinestaticconstexpr

rmw_qos_profile_parameters — KEEP_LAST(1000), RELIABLE, VOLATILE.

rosout()

constexpr QoS rclcpp::detail::qos_table::rosout ( )

inlinestaticconstexpr

rcl_qos_profile_rosout_default — KEEP_LAST(1000), RELIABLE, TRANSIENT_LOCAL, lifespan {10, 0}.

sensor_data()

constexpr QoS rclcpp::detail::qos_table::sensor_data ( )

inlinestaticconstexpr

rmw_qos_profile_sensor_data — KEEP_LAST(5), BEST_EFFORT, VOLATILE.

services_default()

constexpr QoS rclcpp::detail::qos_table::services_default ( )

inlinestaticconstexpr

rmw_qos_profile_services_default — KEEP_LAST(10), RELIABLE, VOLATILE.

The depth is stated rather than inherited from QoS(): upstream states it, and a row that leaves a field to a default cannot be compared to upstream's row field by field.
