<H2>26.4 An Inserter for Phone Numbers</H2>
<A NAME="idx592"><!></A>
<P>Now let's take a look at the implementation of the inserter for our phone number class:</P>

<UL><PRE>
std::ostream&amp; operator&lt;&lt; (std::ostream&amp; os, const PhoneNumber&amp; pn){
  std::locale loc = os.getloc ();                           // 1
  const phone_put&amp; ppFacet 
                     = std::use_facet&lt;phone_put&gt; (loc);     // 2
  os &lt;&lt; ppFacet.put(pn._cntryName,
                    pn._areaCode, pn._extension);           // 3
  return (os);
}
</PRE></UL>
<TABLE CELLPADDING="3">

<TR VALIGN="top"><TD><SAMP>//1</SAMP></TD><TD>The inserter function uses the output stream's locale object (obtained via <SAMP>getloc()</SAMP>), 
<TR VALIGN="top"><TD><SAMP>//2</SAMP></TD><TD>uses the locale's phone number facet object,
<TR VALIGN="top"><TD><SAMP>//3</SAMP></TD><TD>and calls the facet object's formatting service <SAMP>put()</SAMP>.
</TABLE>
