System¶

class yamcs.pymdb.System¶

Bases: object

The top-level system is the root element for the set of metadata necessary to monitor and command a space device, such as a satellite.

A system defines a namespace.

Metadata areas include: telemetry, calibration, alarm, algorithms and commands.

A system may have child Subsystems, forming a system tree.

__init__(name: str, aliases: Optional[Mapping[str, str]] = None, short_description: Optional[str] = None, long_description: Optional[str] = None, extra: Optional[Mapping[str, str]] = None)¶

property algorithms: list[Algorithm]¶: Algorithms directly belonging to this system

aliases: dict[str, str]¶: Alternative names, keyed by namespace

property commands: list[Command]¶: Commands directly belonging to this system

property containers: list[Container]¶: Containers directly belonging to this system

Serialize this system in XTCE format to a file-like object

Parameters:

fp – The file-like object to serialize to. fp.write() must support str input.
indent – String used to indent each level. For most compact, use empty string. Defaults to two spaces.
top_comment – Customize the XML comment to insert at the top of the generated XTCE. Set to false to have no top comment.
skip_algorithms – If True, skip the <AlgorithmSet /> tag within <TelemetryMetaData />.
skip_commands – If True, skip the <CommandMetaData /> tag.
skip_containers – If True, skip the <ContainerSet /> tag within <TelemetryMetaData />.
skip_parameters – If True, skip the <ParameterSet /> and <ParameterTypeSet /> within <TelemetryMetaData />.

dumps(*, indent: str = ' ', top_comment: bool | str = True, skip_algorithms: bool = False, skip_commands: bool = False, skip_containers: bool = False, skip_parameters: bool = False, skip_subsystems: bool = False) → str¶

Serialize this system to an XTCE-formatted string

Parameters:

indent – String used to indent each level. For most compact, use empty string. Defaults to two spaces.
top_comment – Customize the XML comment to insert at the top of the generated XTCE. Set to false to have no top comment.
skip_algorithms – If True, skip the <AlgorithmSet /> tag within <TelemetryMetaData />.
skip_commands – If True, skip the <CommandMetaData /> tag.
skip_containers – If True, skip the <ContainerSet /> tag within <TelemetryMetaData />.
skip_parameters – If True, skip the <ParameterSet /> and <ParameterTypeSet /> within <TelemetryMetaData />.
