tud_lbm.operators.factory
=========================

.. py:module:: tud_lbm.operators.factory

.. autoapi-nested-parse::

   Unified operator factory — single source of truth for operator lookup.

   This module provides a generic factory function that resolves operator names
   to their implementations using the central registry. All operator-specific
   factories (in collision/, streaming/, etc) delegate to this generic factory.

   .. rubric:: Example

   def build_collision_fn(scheme: str) -> CollisionOperator:
       return build_operator("collision_models", scheme)

.. py:function:: build_operator(kind: str, scheme: str) -> tud_lbm.registry.OperatorTarget

   Resolve operator name to implementation.

   This is the single source of truth for operator factory logic.
   All operator-specific factories delegate to this function.

   :param kind: Operator kind ("collision_models", "stream", "equilibrium", etc)
   :param scheme: Operator name within that kind ("bgk", "standard", "wb", etc)

   :returns: The operator function/class satisfying the protocol
   :rtype: OperatorTarget

   :raises ValueError: If kind is not registered or scheme is unknown

   .. rubric:: Example

   >>> op = build_operator("collision_models", "bgk")
   >>> result = op(f, feq, tau)
