49 \brief The QXmlNamePool class is a table of shared strings referenced by instances of QXmlName.
54 QXmlNamePool is used to optimize operations on instances of
55 QXmlName. An instance of QXmlName represents an XML name in
56 a way that allows the XML name to be compared and passed around
57 efficiently. The efficiency is achieved by storing the strings
58 comprising the XML names in an instance of QXmlNamePool, where
59 they are mapped to binary identifiers, which are then packed
60 into a key which is stored in the QXmlName.
62 This means that each instance of QXmlName is tied to the name
63 pool it was created with, and that name pool should be kept in
64 scope and used to create all instances of QXmlName that might
65 be compared. Note also that the name pool is required if you
66 must reconstitute the QXmlName as text, or if you must access
67 any of its component strings, so although instances of
68 QXmlName can be compared without reference to a name pool, the
69 name pool must be kept in scope if the name's strings must be
73 \sa QXmlQuery::namePool()
77 Constructs an empty name pool.
79 QXmlNamePool::QXmlNamePool() : d(new QPatternist::NamePool())
84 Constructs a copy of the \a other name pool.
86 QXmlNamePool::QXmlNamePool(const QXmlNamePool &other) : d(other.d)
91 Destroys the name pool. Instances of QXmlName constructed
92 with this name pool can still be compared after this destructor
93 is called, but their text strings cannot be accessed.
95 QXmlNamePool::~QXmlNamePool()
99 QXmlNamePool::QXmlNamePool(QPatternist::NamePool *namePool) : d(QExplicitlySharedDataPointer<QPatternist::NamePool>(namePool))
104 Assigns the \a other name pool to this one.
106 QXmlNamePool &QXmlNamePool::operator=(const QXmlNamePool &other)
