The locally defined function <A REL=DEFINITION HREF="#next-method-p"><B>next-method-p</B></A> can be used within the body <A REL=DEFINITION HREF="26_glo_f.htm#form"><I>forms</I></A> (but not the <A REL=DEFINITION HREF="26_glo_l.htm#lambda_list"><I>lambda list</I></A>) defined by a <A REL=DEFINITION HREF="26_glo_m.htm#method-defining_form"><I>method-defining form</I></A> to determine whether a next <A REL=DEFINITION HREF="26_glo_m.htm#method"><I>method</I></A> exists. <P>
|
|
The <A REL=DEFINITION HREF="26_glo_f.htm#function"><I>function</I></A> <A REL=DEFINITION HREF="#next-method-p"><B>next-method-p</B></A> has <A REL=DEFINITION HREF="26_glo_l.htm#lexical_scope"><I>lexical scope</I></A> and <A REL=DEFINITION HREF="26_glo_i.htm#indefinite_extent"><I>indefinite extent</I></A>. <P>

Whether or not <A REL=DEFINITION HREF="#next-method-p"><B>next-method-p</B></A> is <A REL=DEFINITION HREF="26_glo_f.htm#fbound"><I>fbound</I></A> in the <A REL=DEFINITION HREF="26_glo_g.htm#global_environment"><I>global environment</I></A> is <A REL=DEFINITION HREF="26_glo_i.htm#implementation-dependent"><I>implementation-dependent</I></A>; however, the restrictions on redefinition and <I>shadowing</I> of <A REL=DEFINITION HREF="#next-method-p"><B>next-method-p</B></A> are the same as for <A REL=DEFINITION HREF="26_glo_s.htm#symbol"><I>symbols</I></A> in the <TT>COMMON-LISP</TT> package which are <A REL=DEFINITION HREF="26_glo_f.htm#fbound"><I>fbound</I></A> in the <A REL=DEFINITION HREF="26_glo_g.htm#global_environment"><I>global environment</I></A>. The consequences of attempting to use <A REL=DEFINITION HREF="#next-method-p"><B>next-method-p</B></A> outside of a <A REL=DEFINITION HREF="26_glo_m.htm#method-defining_form"><I>method-defining form</I></A> are undefined. <P>
