46 \class QXmlNamePool
47 \brief The QXmlNamePool class is a table of shared strings referenced by instances of QXmlName.
48 \reentrant
49 \since 4.4
50 \ingroup xml-tools
51 \inmodule QtXmlPatterns
52
53 QXmlNamePool is used to optimize operations on instances of
54 QXmlName. An instance of QXmlName represents an XML name in
55 a way that allows the XML name to be compared and passed around
56 efficiently. The efficiency is achieved by storing the strings
57 comprising the XML names in an instance of QXmlNamePool, where
58 they are mapped to binary identifiers, which are then packed
59 into a key which is stored in the QXmlName.
60
61 This means that each instance of QXmlName is tied to the name
62 pool it was created with, and that name pool should be kept in
63 scope and used to create all instances of QXmlName that might
64 be compared. Note also that the name pool is required if you
65 must reconstitute the QXmlName as text, or if you must access
66 any of its component strings, so although instances of
67 QXmlName can be compared without reference to a name pool, the
68 name pool must be kept in scope if the name's strings must be
69 accessed later.
