7.7.29 next-method-p Local Function

next-method-p < no arguments >    generalized-boolean

Arguments and Values:
generalized-boolean - a generalized boolean.

The locally defined function next-method-p can be used within the body forms (but not the lambda list) defined by a method-defining form to determine whether a next method exists.

The function next-method-p has lexical scope and indefinite extent.

Whether or not next-method-p is fbound in the global environment is implementation-dependent; however, the restrictions on redefinition and shadowing of next-method-p are the same as for symbols in the common-lisp package which are fbound in the global environment. The consequences of attempting to use next-method-p outside of a method-defining form are undefined.

call-next-method, defmethod, call-method
