Functions

atomicValue()

QVariant AbstractXmlPullProvider::atomicValue ( ) const

pure virtual

If current() event is AtomicValue, the atomic value is returned as a QVariant.

In all other cases, this function returns a null QVariant.

Implemented in QPatternist::PullBridge.

attributeItems()

virtual QHash<QXmlName, QXmlItem> QPatternist::AbstractXmlPullProvider::attributeItems ( )

pure virtual

Implemented in QPatternist::PullBridge.

attributes()

QHash< QXmlName, QString > AbstractXmlPullProvider::attributes ( )

pure virtual

If the current() is Element, the attributes of the element are returned, an empty list of attributes otherwise.

Implemented in QPatternist::PullBridge.

current()

Event AbstractXmlPullProvider::current ( ) const

pure virtual

Returns the event that next() returned the last time it was called.

It doesn't alter this AbstractXmlPullProvider.

current() may not modify this AbstractXmlPullProvider's state. Subsequent calls to current() must return the same value.

See also

AbstractXmlPullProvider::Event

Implemented in QPatternist::PullBridge.

name()

QName AbstractXmlPullProvider::name ( ) const

pure virtual

If the current event is StartElement, EndElement, ProcessingInstruction, Attribute, or Namespace, the node's name is returned.

If the current event is ProcessingInstruction, the processing instruction target is in in the local name.

If the current event is Namespace, the name's namespace URI is the namespace, and the local name is the prefix the name is binding to.

In all other cases, an invalid QName is returned.

Implemented in QPatternist::PullBridge.

next()

Event AbstractXmlPullProvider::next ( )

pure virtual

Advances this AbstractXmlPullProvider, and returns the new event.

See also

current()

Implemented in QPatternist::PullBridge.

stringValue()

QString AbstractXmlPullProvider::stringValue ( ) const

pure virtual

If current() is Text, the text node's value is returned.

If the current() event is Comment, its value is returned. The subclasser guarantees it does not contain the string "-->".

If the current() event is ProcessingInstruction, its data is returned. The subclasser guarantees the data does not contain the string "?>".

In other cases, it returns a default constructed string.

Implemented in QPatternist::PullBridge.
