|
---|
| 49 | \brief The QXmlNamePool class is a table of shared strings referenced by instances of QXmlName.
|
---|
| 50 | \reentrant
|
---|
| 51 | \since 4.4
|
---|
| 52 | \ingroup xml-tools
|
---|
| 53 |
|
---|
| 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.
|
---|
| 61 |
|
---|
| 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
|
---|
| 70 | accessed later.
