class as2fm.scxml_converter.scxml_entries.scxml_ros_action_server.RosActionStartThread(interface_decl: str | RosDeclaration, fields: List[RosField], additional_args: Dict[str, str] | None = None)

Bases: RosTrigger

Object representing the request, from an action server, to start a new execute thread instance.

__init__(interface_decl: str | RosDeclaration, fields: List[RosField], additional_args: Dict[str, str] | None = None) → None

Constructor of a generic ROS trigger.

Parameters:

interface_decl – ROS interface declaration to be used in the trigger, or its name.
fields – Name of fields that are sent together with the trigger.
additional_args – Additional arguments in the SCXML-ROS tag.
