Functions

load

Each loaded instance, DTS, testcase, testsuite, versioning report, or RSS feed, is represented by an instance of a ModelXbrl object. The ModelXbrl object has a collection of ModelDocument objects, each representing an XML document (for now, with SQL whenever its time comes). One of the modelDocuments of the ModelXbrl is the entry point (of discovery or of the test suite).

Each loaded instance, DTS, testcase, testsuite, versioning report, or RSS feed, is represented by an instance of a ModelXbrl object. The ModelXbrl object has a collection of ModelDocument objects, each representing an XML document (for now, with SQL whenever its time comes). One of the modelDocuments of the ModelXbrl is the entry point (of discovery or of the test suite).

Parameters:

  • url – may be a filename or FileSource object

  • nextaction – text to use as status line prompt on conclusion of loading and discovery

  • base – the base URL if any (such as a versioning report’s URL when loading to/from DTS modelXbrl).

  • useFileSource – for internal use (when an entry point is in a FileSource archive and discovered files expected to also be in the entry point’s archive.

error(codes: str | tuple[str, ...], msg: str, **args: Any) → None

Logs a message as info, by code, logging-system message text (using %(name)s named arguments to compose string by locale language), resolving model object references (such as qname), to prevent non-dereferencable memory usage. Supports logging system parameters, and special parameters modelObject, modelXbrl, or modelDocument, to provide trace information to the file, source line, and href (XPath element scheme pointer). Supports the logging exc_info argument.

Args may include a specification of one or more ModelObjects that identify the source of the message, as modelObject={single-modelObject, (sequence-of-modelObjects)} or modelXbrl=modelXbrl or modelDocument=modelDocument.

Args must include a named argument for each msg %(namedArg)s replacement.

Parameters:

  • codes – Message code or tuple/list of message codes

  • msg – Message text string to be formatted and replaced with named parameters in **args

  • **args – Named arguments including modelObject, modelXbrl, or modelDocument, named arguments in msg string, and any exc_info argument.

  • messageCodes – If first parameter codes, above, is dynamically formatted, this is a documentation string of the message codes only used for extraction of the message catalog document (not used in run-time processing).

exception(codes: str | tuple[str, ...], msg: str, **args: str) → None

Same as error(), but as exception

profileActivity(activityCompleted: str | None = None, minTimeToShow: float = 0) → None

Used to provide interactive GUI messages of long-running processes.

When the time between last profileActivity and this profileActivity exceeds minTimeToShow, then the time is logged (if it is shorter than it is not logged), thus providing feedback of long running (and possibly troublesome) processing steps.

Parameters:

  • activityCompleted – Description of activity completed, or None if call is just to demark starting of a profiled activity.

  • minTimeToShow – Seconds of elapsed time for activity, if longer then the profile message appears in the log.

saveDTSpackage() → None
