const NamespaceResolver::Ptr & staticNamespaces() const
static QXmlName expandQName(const QString &lexicalQName, const TReportContext &context, const NamespaceResolver::Ptr &nsResolver, const SourceLocationReflection *const r, const bool asForAttribute=false)
The QString class provides a Unicode character string.
Definition: qstring.h:83
bool contains(const Key &key) const
Returns true if the hash contains an item with the key; otherwise returns false.
Definition: qhash.h:872
const char * name
QString stringValue() const
Returns the string value of this Item.
Definition: qitem_p.h:302
static Boolean::Ptr fromValue(const bool value)
Definition: qboolean.cpp:115
T & first()
Returns a reference to the first item in the list.
Definition: qlist.h:282
