1.4.4.5 The ``Class Precedence List'' Section of a Dictionary Entry</H2> <P>
|
|
This appears in the dictionary entry for a <A REL=DEFINITION HREF="26_glo_c.htm#class"><I>class</I></A>, and contains an ordered list of the <A REL=DEFINITION HREF="26_glo_c.htm#class"><I>classes</I></A> defined by Common Lisp that must be in the <A REL=DEFINITION HREF="26_glo_c.htm#class_precedence_list"><I>class precedence list</I></A> of this <A REL=DEFINITION HREF="26_glo_c.htm#class"><I>class</I></A>. <P>
|
|
It is permissible for other (<A REL=DEFINITION HREF="26_glo_i.htm#implementation-defined"><I>implementation-defined</I></A>) <A REL=DEFINITION HREF="26_glo_c.htm#class"><I>classes</I></A> to appear in the <A REL=DEFINITION HREF="26_glo_i.htm#implementation"><I>implementation</I></A>'s <A REL=DEFINITION HREF="26_glo_c.htm#class_precedence_list"><I>class precedence list</I></A> for the <A REL=DEFINITION HREF="26_glo_c.htm#class"><I>class</I></A>. <P>
|
|
It is permissible for either <A REL=DEFINITION HREF="t_std_ob.htm#standard-object"><B>standard-object</B></A> or <A REL=DEFINITION HREF="t_stu_ob.htm#structure-object"><B>structure-object</B></A> to appear in the <A REL=DEFINITION HREF="26_glo_i.htm#implementation"><I>implementation</I></A>'s <A REL=DEFINITION HREF="26_glo_c.htm#class_precedence_list"><I>class precedence list</I></A>; for details, see <A REL=CHILD HREF="04_bb.htm">Section 4.2.2 (Type Relationships)</A>. <P>
|
|
Except as explicitly indicated otherwise somewhere in this specification, no additional <A REL=DEFINITION HREF="26_glo_s.htm#standardized"><I>standardized</I></A> <A REL=DEFINITION HREF="26_glo_c.htm#class"><I>classes</I></A> may appear in the <A REL=DEFINITION HREF="26_glo_i.htm#implementation"><I>implementation</I></A>'s <A REL=DEFINITION HREF="26_glo_c.htm#class_precedence_list"><I>class precedence list</I></A>. <P>
|
|
By definition of the relationship between <A REL=DEFINITION HREF="26_glo_c.htm#class"><I>classes</I></A> and <A REL=DEFINITION HREF="26_glo_t.htm#type"><I>types</I></A>, the <A REL=DEFINITION HREF="26_glo_c.htm#class"><I>classes</I></A> listed in this section are also <A REL=DEFINITION HREF="26_glo_s.htm#supertype"><I>supertypes</I></A> of the <A REL=DEFINITION HREF="26_glo_t.htm#type"><I>type</I></A> denoted by the <A REL=DEFINITION HREF="26_glo_c.htm#class"><I>class</I></A>. <P>
