- <P>Valued sets are an extension of the traditional set concept. In
- addition to a member just existing in the set, the member also has a
- distinct value. You can think of this a combination of a traditional
- set and a Perl hash.</P>
- <P>The used methods are as for the traditional of Set::Scalar, with
- the difference that when creating (new()) or modifying (insert(),
- delete(), invert()), you must supply twice the number of arguments:
- the member-value pairs, instead of just the members. Note, though,
- that in the current implementation of <A HREF="../../../../lib/Pod/perlfunc.html#item_delete"><CODE>delete()</CODE></A> the value half is
- unused, the deletion is by the member. In future implementation
- this behavior may change so that also the value matters.</P>
- <P>There are a couple of additional methods:</P>
- <PRE>
- %ve = $s->valued_members;</PRE>
- <P>which returns the member-value pairs, and</P>
- <PRE>
- @v = $s->values;</PRE>
- <P>which returns just the values (in the same order as the <CODE>members()</CODE>
- method would return the members), and</P>
- <PRE>
- $v = $s->value($member);</PRE>
- <P>which returns the value of the member.</P>
- <P>The display format of a valued set is the member-value pairs separated
- by `` => '', the pairs separated by ``, '' and enclosed in curly brackets {}.</P>
