Metadata Class

Metadata is a class that handles addition and removal of measurement-level metadata and parameters.

When used as a context manager, the Logging Library automatically removes the metadata and parameters that were added within the scope of the Metadata instance. This can be done using the with statement: 

with run.Metadata() as loop1:
    for mode in modes:
        loop1.add_string_parameter(
            parameter_name="Mode",
            parameter_value=mode
            )

        loop1.add_metadata(
            metadata_name=Fields.LotName,
            metadata_value="Lot_2"
            )

        perform_measurement()

        run.log_measurement(measurement)

If not using the with statement, metadata and parameters added to the Metadata object must be removed explicitly:

loop1 = run.Metadata()
for mode in modes:
    loop1.add_string_parameter(
        parameter_name="Mode",
        parameter_value=mode
        )

    loop1.add_metadata(
        metadata_name=Fields.LotName,
        metadata_value="Lot_2"
        )

    perform_measurement()

    run.log_measurement(measurement)

loop1.remove_all_metadata()
loop1.remove_all_parameters()
Note You can use the get_parameters() and get_metadata() functions to retrieve information from the respective property.
