_process_invite(req)

Todo:This needs better arranging for logic. Currently it ignores whitelists/blacklists if the local_remote_controllers

only is flagged. Not an urgent use case though.

To fix, just do abort checks for local remote controllers first, then put it through the rest of the logic as well.

Parameters:req (rapp_manager_srvs.InviteRequest) – Invitation request Returns:Response Return type:rapp_manager_srvs.InviteResponse

_process_stop_app(req=None)

Stops a currently running rapp. This can be triggered via the stop_app service call (in which case req is configured), or if the rapp monitoring thread detects that it has naturally stopped by itself (in which case req is None).

Parameters:req – variable configured when triggered from the service call.

_publish_rapp_list()

Publishes an updated list of available apps (in that order).

_publish_status()

Publish status updates whenever something significant changes, e.g. remote controller changed, or rapp started/stopped.

_set_platform_info()

Initialises the rapp manager with the appropriate platform info. This is part of the __init__ process.
