next-method-p ⟨no arguments⟩ → generalized-boolean

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.
