by instances of <a href="qxmlname.html">QXmlName</a>.</p>
<p>QXmlNamePool is used to optimize operations on instances of
<a href="qxmlname.html">QXmlName</a>. An instance of <a href="qxmlname.html">QXmlName</a> represents an XML name in a way that
allows the XML name to be compared and passed around efficiently.
The efficiency is achieved by storing the strings comprising the
XML names in an instance of QXmlNamePool, where they are mapped to
binary identifiers, which are then packed into a key which is
stored in the <a href="qxmlname.html">QXmlName</a>.</p>
<p>This means that each instance of <a href="qxmlname.html">QXmlName</a> is tied to the name pool it was
created with, and that name pool should be kept in scope and used
to create all instances of <a href="qxmlname.html">QXmlName</a>
that might be compared. Note also that the name pool is required if
you must reconstitute the <a href="qxmlname.html">QXmlName</a> as
text, or if you must access any of its component strings, so
although instances of <a href="qxmlname.html">QXmlName</a> can be
compared without reference to a name pool, the name pool must be
kept in scope if the name's strings must be accessed later.</p>
