mafw.processor.meta

Metaclass for the Processor framework.

This module defines ProcessorMeta, the metaclass responsible for finalising every Processor subclass at creation time. Its duties include:

  • Ensuring parameter definitions are properly inherited and registered.

  • Validating any declared filter schema against the allowed model constraints.

  • Installing the super-call wrappers that guard method execution at runtime.

  • Invoking __post_init__() after each instance is constructed.

Added in version 2.3: Extracted from the monolithic processor.py module for improved maintainability and focused testing.

Classes

ProcessorMeta(name, bases, namespace)

Metaclass that finalizes Processor subclasses before instantiation.
class mafw.processor.meta.ProcessorMeta(name: str, bases: tuple[type, ...], namespace: dict[str, Any])[source]

Bases: type

Metaclass that finalizes Processor subclasses before instantiation.

Set up new Processor subclasses.

This method first checks the class for well-formed parameter definitions and filter metadata, then runs the super-call wrapping machinery described below. The wrappers are installed at class-creation time so that any later instance will be guarded before it even starts executing.
