\class QXmlNamePool
\brief The QXmlNamePool class is a table of shared strings referenced by instances of QXmlName.
\reentrant
\since 4.4
\ingroup xml-tools
QXmlNamePool is used to optimize operations on instances of
QXmlName. An instance of QXmlName 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 QXmlName.
This means that each instance of QXmlName 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 QXmlName that might
be compared. Note also that the name pool is required if you
must reconstitute the QXmlName as text, or if you must access
any of its component strings, so although instances of
QXmlName 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.
