4.4 Method Definition

define-method (syntax)

• add-method! target method (generic)

  define-method invokes the add-method! generic function to handle adding the new method to a variety of possible targets. GOOPS includes methods to handle target as

  • a generic function (the most common case)

  • a procedure

  • a primitive generic (see section 3.5.3 Extending Guile's Primitives)

  By defining further methods for add-method!, you can theoretically handle adding methods to further types of target.
