9.1.4.2.4 Associating a Restart with a Condition</H2> <P>
|
|
A <A REL=DEFINITION HREF="26_glo_r.htm#restart"><I>restart</I></A> can be ``associated with'' a <A REL=DEFINITION HREF="26_glo_c.htm#condition"><I>condition</I></A> explicitly by <A REL=DEFINITION HREF="m_w_cnd_.htm#with-condition-restarts"><B>with-condition-restarts</B></A>, or implicitly by <A REL=DEFINITION HREF="m_rst_ca.htm#restart-case"><B>restart-case</B></A>. Such an assocation has <A REL=DEFINITION HREF="26_glo_d.htm#dynamic_extent"><I>dynamic extent</I></A>. <P>
|
|
A single <A REL=DEFINITION HREF="26_glo_r.htm#restart"><I>restart</I></A> may be associated with several <A REL=DEFINITION HREF="26_glo_c.htm#condition"><I>conditions</I></A> at the same time. A single <A REL=DEFINITION HREF="26_glo_c.htm#condition"><I>condition</I></A> may have several associated <A REL=DEFINITION HREF="26_glo_r.htm#restart"><I>restarts</I></A> at the same time. <P>
|
|
Active restarts associated with a particular <A REL=DEFINITION HREF="26_glo_c.htm#condition"><I>condition</I></A> can be detected by <I>calling</I> a <A REL=DEFINITION HREF="26_glo_f.htm#function"><I>function</I></A> such as <A REL=DEFINITION HREF="f_find_r.htm#find-restart"><B>find-restart</B></A>, supplying that <A REL=DEFINITION HREF="26_glo_c.htm#condition"><I>condition</I></A> as the <I>condition</I> <A REL=DEFINITION HREF="26_glo_a.htm#argument"><I>argument</I></A>. Active restarts can also be detected without regard to any associated <A REL=DEFINITION HREF="26_glo_c.htm#condition"><I>condition</I></A> by calling such a function without a <I>condition</I> <A REL=DEFINITION HREF="26_glo_a.htm#argument"><I>argument</I></A>, or by supplying a value of <A REL=DEFINITION HREF="a_nil.htm#nil"><B>nil</B></A> for such an <A REL=DEFINITION HREF="26_glo_a.htm#argument"><I>argument</I></A>. <P>
