• get compatible(): QoSProfile

  Get most compatible QoS profile with Reliability set to BEST_EFFORT. Values are: HistoryPolicy = KEEP_LAST, depth = 10, ReliabilityPolicy = BEST_EFFORT, DurabilityPolicy = VOLATILE, deadline = QoSProfile.DurationUnspecified, lifespan = QoSProfile.DurationUnspecified, LivelinessPolicy = SYSTEM_DEFAULT, liveliness_lease_duration = QoSProfile.DurationUnspecified, avoid_ros_namespace_conventions = false

  Returns QoSProfile

  QoSProfile

Staticdefault

• get default(): QoSProfile

  Get default profile. Default values are: HistoryPolicy = KEEP_LAST, depth = 10, ReliabilityPolicy = RELIABLE, DurabilityPolicy = VOLATILE, deadline = QoSProfile.DurationUnspecified, lifespan = QoSProfile.DurationUnspecified, LivelinessPolicy = SYSTEM_DEFAULT, liveliness_lease_duration = QoSProfile.DurationUnspecified, avoid_ros_namespace_conventions = false

  Returns QoSProfile
