inline

Publish a message using a run-time defined DynamicGroup (const reference variant). Where possible, prefer the static variant in StaticTransporterInterface::publish()

Template Parameters

Data	data type to publish. Can usually be inferred from the `data` parameter.
scheme	Marshalling scheme id (typically MarshallingScheme::MarshallingSchemeEnum). Can usually be inferred from the Data type.

Parameters

data	Message to publish
group	group to publish this message to (typically a DynamicGroup). If a Publisher is provided, the group will be set in the data using Publisher::set_group()
publisher	Optional metadata that controls the publication or sets callbacks to monitor the result.
