compute-effective-method generic-function method-combination methods => effective-method, options,

Arguments and values:

generic-function -- A generic function metaobject.

method-combination -- A method combination metaobject.

methods -- A list of method metaobjects.

effective-method -- An effective method.

options -- A list of effective method options.


This generic function is called to determine the effective method from a sorted list of method metaobjects.

An effective method is a form that describes how the applicable methods are to be combined. Inside of effective method forms are call-method forms which indicate that a particular method is to be called. The arguments to the call-method form indicate exactly how the method function of the method should be called. (See make-method-lambda for more details about method functions.)

An effective method option has the same interpretation and syntax as either the :arguments or the :generic-function option in the long form of define-method-combination.

More information about the form and interpretation of effective methods and effective method options can be found under the description of the define-method-combination macro in the CLOS specification.

This generic function can be called by the user or the implementation. It is called by discriminating functions whenever a sorted list of applicable methods must be converted to an effective method.
