Functions

◆ addBinding()

void DelegatingNamespaceResolver::addBinding ( const QXmlName nb )

virtual

Adds the mapping from prefix to namespaceURI to this NamespaceResolver. If this NamespaceResolver already contains a binding involving prefix, the old binding is replaced.

Implements QPatternist::NamespaceResolver.

Definition at line 84 of file qdelegatingnamespaceresolver.cpp.

 {
     if(nb.namespaceURI() == StandardNamespaces::UndeclarePrefix)
         m_bindings.remove(nb.prefix());
     else
         m_bindings.insert(nb.prefix(), nb.namespaceURI());
 }

◆ bindings()

NamespaceResolver::Bindings DelegatingNamespaceResolver::bindings ( ) const

virtual

Returns: all bindings this NamespaceResolver handles.

Implements QPatternist::NamespaceResolver.

Definition at line 72 of file qdelegatingnamespaceresolver.cpp.

 {
     Bindings bs(m_nsResolver->bindings());
     const Bindings::const_iterator end(m_bindings.constEnd());
     Bindings::const_iterator it(m_bindings.constBegin());
 
     for(; it != end; ++it)
         bs.insert(it.key(), it.value());
 
     return bs;
 }

◆ lookupNamespaceURI()

QXmlName::NamespaceCode DelegatingNamespaceResolver::lookupNamespaceURI ( const QXmlName::PrefixCode prefix ) const

virtual

Resolves the prefix to the corresponding namespace URI. If no binding exists for prefix, NoBinding is returned.

Returns: the namespace corresponding to prefix.

Implements QPatternist::NamespaceResolver.

Definition at line 62 of file qdelegatingnamespaceresolver.cpp.

 {
     const QXmlName::NamespaceCode val(m_bindings.value(prefix, NoBinding));
 
     if(val == NoBinding)
         return m_nsResolver->lookupNamespaceURI(prefix);
     else
         return val;
 }
