| \class QXmlNamePool |
| \brief The QXmlNamePool class is a table of shared strings referenced by instances of QXmlName. |
| \reentrant |
| \since 4.4 |
| \ingroup xml-tools |
| \inmodule QtXmlPatterns |
| |
| 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. |
