Component node object.
Node representing a component on a name server. Component nodes can occur below name server and directory nodes. They cannot contain any children. Component nodes store all the properties of a component, as well as references to the actual objects and object types used in the component. This node can be made dynamic by setting the 'dynamic' property to True. The following callbacks are available on this node type when it is dynamic: - rtc_status(ec_handle, status) The component's state has changed in the specified execution context. The new status is one of Component.INACTIVE, Component.ACTIVE, Component.ERROR, Component.UNKNOWN and Component.CREATED. - component_profile(items) One or more members of the component's profiles have been updated. The updated items are listed in the "items" argument. - ec_event(ec_handle, event) A change in one of the attached execution contexts has occurred. The event is one of Component.EC_ATTACHED, Component.EC_DETACHED, Component.EC_RATE_CHANGED, Component.EC_STARTUP, and Component.EC_SHUTDOWN. - port_event(port_name, event) A change on the specified port has occurred. The event is one of Component.PORT_ADD, Component.PORT_REMOVE, Component.PORT_CONNECT and Component.PORT_DISCONNECT. - config_event(config_set_name, event) A change in the component's configuration sets has occurred. The event is one of Component.CFG_UPDATE_SET, Component.CFG_UPDATE_PARAM, Component.CFG_UPDATE_PARAM_IN_ACTIVE, Component.CFG_ADD_SET, Component.CFG_REMOVE_SET and Component.CFG_ACTIVATE_SET. - heartbeat(time) A heartbeat was received from the component. The time the beat was received is passed.
