NormalizationIndexEntry Class Documentation

NormalizationIndexEntry.py introduces NormalizationIndexEntry, a class for encapsulating normalization index entries. It models entries through attributes like runNumber, backgroundRunNumber, version, appliesTo, comments, author, and timestamp, and includes appliesToFormatChecker, a validation method to ensure the appliesTo attribute conforms to the expected format.

Initialization requires no explicit inputs; attributes are set by providing values upon instantiation, resulting in a fully populated object reflecting the specified attributes.

The appliesToFormatChecker method validates the appliesTo attribute’s format against ‘runNumber’, ‘>runNumber’, or ‘<runNumber’, ensuring correct data incorporation by examining the attribute’s prefix and validating the subsequent string as a legitimate integer run number. A ValueError is raised for format mismatches, maintaining data integrity.

Attributes:

  • runNumber (str): Unique identifier for the run. This is used to distinguish between different normalization entries and ensure each is properly associated with its corresponding run.

  • backgroundRunNumber (str): Identifier for the background run associated with this entry, facilitating the differentiation and contextual understanding of normalization data.

  • version (Optional[str]): Version of the entry; optional. Allows for version tracking of the normalization entry for updates and revisions.

  • appliesTo (Optional[str]): Specifies applicable run numbers in ‘runNumber’, ‘>runNumber’, or ‘<runNumber’ format; optional. The format is validated to ensure consistency and correctness.

  • comments (Optional[str]): Additional comments about the entry; optional. Provides a space for annotating the entry with relevant observations or notes.

  • author (Optional[str]): Author’s name who created or modified the entry; optional. Records the individual responsible for the entry, aiding in traceability.

  • timestamp (Optional[float]): Unix timestamp of creation or last update; optional.Timestamps offer temporal context to the entry’s creation or modification.

Validator Logic:

Validates the ‘appliesTo’ format: ‘runNumber’, ‘>runNumber’, or ‘<runNumber’.

Ensures that the ‘appliesTo’ attribute, if present, follows a predefined format for consistency and correctness across entries. Raises a ValueError if the format does not match expectations, safeguarding against invalid data entry.

Parameters:

  • v (str): testValue

    The value to validate, representing the ‘appliesTo’ field.

Outputs:

Returns the validated value, confirming it adheres to the correct format.
