public class QXmlNamePool

The QXmlNamePool
class is a table of shared strings referenced by instances of QXmlName
. 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.
