lenskit.pipeline.components.Placeholder
=======================================

.. py:class:: lenskit.pipeline.components.Placeholder(config = None, **kwargs)
   

   Bases: :py:obj:`Component`\ [\ :py:obj:`Any`\ ]


   Simple no-op component to use as a placeholder in partial pipelines.


   .. py:attribute:: config
      :type:  PlaceholderConfig

      The component configuration object.  Component classes that support
      configuration **must** redefine this attribute with their specific
      configuration class type, which can be a Python dataclass or a Pydantic
      model class.


   .. py:method:: __call__(**kwargs)
      :abstractmethod:


      Run the pipeline's operation and produce a result.  This is the key
      method for components to implement.
