4.2.9.2. Duration type configuration

This section explains how to access the different configurable parameters in a duration type configuration. The scope of this section does not include explaining the usage of these specific parameters. Please, refer to Fast DDS documentation for that information.

The duration type configuration is accessed through the duration element which is a complex parameter according to the Configuration parameter classification. The duration type configurable <subelements> are explained in the table below.

subelement	CLI access	Configuration parameter classification	Valid set values
Seconds	duration.<duration_type>.sec	Simple parameter	int32_t
Nanoseconds	duration.<duration_type>.nanosec	Simple parameter	uint32_t

Duration type can also be set in the following supported usages:

• Setting an infinite duration: duration.<duration_type> infinite

• Setting the duration directly: duration.<duration_type> <sec_value> <nanosec_value>

Note

The duration can be directly set also by passing only the <sec_value> argument: duration.<duration_type> <sec_value>

The <duration_type> element is defined for each specific element. The list below includes the currently supported <duration_type> elements:

• Reliability QoS maximum blocking time.

• Participant builtin discovery configuration lease duration.

• Participant builtin discovery configuration lease announcements.

Warning

Any other <duration_type> is not yet supported.
