MOP Generic Functions
---------------------

The MOP is itself implemented using generic functions and the *class*
slot from each instance.

.. idio:currentmodule:: object

Initialization
^^^^^^^^^^^^^^

.. _`object/initialize`:

.. idio:generic:: object/initialize inst initargs


   
   
   Initialize the instance `inst` from `initargs`.  ``initialize`` is
   called from :ref:`make-instance <object/make-instance>`.
   
   The following methods are defined:
   
   * ``(<method> <top>)``
   
   * ``(<generic> <top>)``
   
   * ``(<class> <top>)``
   
   * ``(<object> <top>)``
   


.. idio:currentmodule:: object

Instance Structure
^^^^^^^^^^^^^^^^^^

.. _`object/allocate-instance`:

.. idio:generic:: object/allocate-instance cl


   
   
   Allocate space for an instance of class `cl`.  ``allocate-instance``
   is called from :ref:`make-instance <object/make-instance>`.
   
   The following methods are defined:
   
   * ``(<entity-class>)``
   
   * ``(<class>)``
   


.. _`object/compute-getter-and-setter`:

.. idio:generic:: object/compute-getter-and-setter cl slot allocator


   
   
   Compute the getter and setter information for slot `slot` in class
   `cl` using allocator `allocator`.
   
   The following method is defined:
   
   * ``(<class> <top> <top>)``
   


.. idio:currentmodule:: object

Class Initialization
^^^^^^^^^^^^^^^^^^^^

.. _`object/compute-cpl`:

.. idio:generic:: object/compute-cpl cl


   
   
   Determine the class precedence list from the super-classes.
   
   The following method is defined:
   
   * ``(<class>)``
   


.. _`object/compute-slots`:

.. idio:generic:: object/compute-slots cl


   
   
   Determine the actual class slots from the direct and inherited slots.
   
   The following method is defined:
   
   * ``(<class>)``
   


.. idio:currentmodule:: object

Generic Invocation
^^^^^^^^^^^^^^^^^^

.. _`object/compute-apply-generic`:

.. idio:generic:: object/compute-apply-generic gf


   
   
   Return a function to be used as the instance proc for generic `gf`.
   
   The function takes any number of arguments and calls
   :ref:`compute-methods <object/compute-methods>` and
   :ref:`compute-apply-methods <object/compute-apply-methods>`.
   
   The following method is defined:
   
   * ``(<generic>)``
   


.. _`object/compute-methods`:

.. idio:generic:: object/compute-methods gf


   
   
   Return a function to be used to calculate the sorted list of methods
   given the generic function's arguments.
   
   The function calls :ref:`compute-method-more-specific?
   <object/compute-method-more-specific?>`.
   
   The following method is defined:
   
   * ``(<generic>)``
   


.. _`object/compute-method-more-specific?`:

.. idio:generic:: object/compute-method-more-specific? gf


   
   
   Return a function to be used to sort methods by their specializers.
   
   The following method is defined:
   
   * ``(<generic>)``
   


.. _`object/compute-apply-methods`:

.. idio:generic:: object/compute-apply-methods gf


   
   
   Return a function to be used to call the :ref:`method-procedure
   <object/method-procedure>` for the sorted list of applicable methods
   determined previously.
   
   The function takes a list of methods and the generic function's
   arguments.
   
   The following method is defined:
   
   * ``(<generic>)``
