詳細描述

The QSimpleXmlNodeModel class is an implementation of QAbstractXmlNodeModel sufficient for many common cases.

子類化 QAbstractXmlNodeModel can be a significant task, because it requires implementing several, complex member functions. QSimpleXmlNodeModel provides default implementations of these member functions that are suitable for a wide range of node models.

子類化的 QSimpleXmlNodeModel must be thread-safe.

QSimpleXmlNodeModel:: QSimpleXmlNodeModel (const QXmlNamePool & namePool )

構造 QSimpleXmlNodeModel for use with with the specified namePool .

[虛擬] QSimpleXmlNodeModel:: ~QSimpleXmlNodeModel ()

析構函數。

[虛擬] QUrl QSimpleXmlNodeModel:: baseUri (const QXmlNodeModelIndex & node ) const

重實現自 QAbstractXmlNodeModel::baseUri ().

Returns the base URI for node . This is always the document URI.

另請參閱 documentUri ().

[虛擬] QXmlNodeModelIndex QSimpleXmlNodeModel:: elementById (const QXmlName & id ) const

重實現自 QAbstractXmlNodeModel::elementById ().

Always returns a default constructed QXmlNodeModelIndex instance, regardless of id .

This effectively means the model has no elements that have an id.

QXmlNamePool &QSimpleXmlNodeModel:: namePool () const

Returns the name pool associated with this model. The implementation of name () will use this name pool to create names.

[虛擬] QVector < QXmlName > QSimpleXmlNodeModel:: namespaceBindings (const QXmlNodeModelIndex & node ) const

重實現自 QAbstractXmlNodeModel::namespaceBindings ().

Always returns an empty QVector . This signals that no namespace bindings are in scope for node .

[虛擬] QVector < QXmlNodeModelIndex > QSimpleXmlNodeModel:: nodesByIdref (const QXmlName & idref ) const

重實現自 QAbstractXmlNodeModel::nodesByIdref ().

Always returns an empty vector, regardless of idref .

This effectively means the model has no elements or attributes of type IDREF .

[虛擬] QString QSimpleXmlNodeModel:: stringValue (const QXmlNodeModelIndex & node ) const

重實現自 QAbstractXmlNodeModel::stringValue ().

若 node is an element or attribute, typedValue () is called, and the return value converted to a string, as per XQuery 's rules.

若 node is another type of node, the empty string is returned.

If this function is overridden for comments or processing instructions, it is important to remember to call it (for elements and attributes having values not of type xs:string ) to ensure that the values are formatted according to XQuery .
