Generic Function

Summary

Returns the discriminating function.

Package

clos

Signature

compute-discriminating-function gf => result

Arguments

gf

A generic function.

Values

result

A function.

Description

The generic function compute-discriminating-function returns the discriminator as specified in AMOP.

However, there are two discrepancies with the AMOP behavior:

• The discriminating function does not compute-applicable-methods-using-classes , since this is not implemented.
• add-method does not call compute-discriminating-function. Instead, it is called when the generic function is called. This is more efficent than calling compute-discriminating-function each time add-method is called.
