4.2.3. DataWriter profiles configuration access¶

This section explains how to access the different configurable parameters in a DataWriter profile. 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 DataWriter profile is accessed through the datawriter element. The profile name is mandatory and must be passed within brackets. Whitespaces are allowed in the profile name if the profile name is quoted. Consequently, datawriter is a complex parameter map according to the Configuration parameter classification with the profile name as key.

Important

The only case when the profile name is not required is when printing or clearing the default profile attribute.

fastddsqosprof <file> <verb> datawriter[profile_name].<subelement>
fastddsqosprof <file> <verb> datawriter["profile name"].<subelement>

The currently supported DataWriter configurable <subelements> are explained in the table below.

`<subelement>`	CLI access	Configuration parameter classification	Valid `set` values
Default profile attribute	`datawriter[(profile_name)].default_profile`	Simple parameter	`true` `false` (`profile_name` is only required with verb `set`).
QoS configuration	`datawriter[profile_name].qos`	Complex parameter. Please, refer to QoS configuration section for more information.	N/A

Warning

Any other configurable <subelement> is not yet supported.
