Syntax:
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.
Description:
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.
