}

attributes()

QVector< QXmlNodeModelIndex > XsdValidatedXmlNodeModel::attributes ( const QXmlNodeModelIndex &  element ) const

protectedvirtual

Returns the attributes of element.

The caller guarantees that element is an element in this node model.

Implements QAbstractXmlNodeModel.

Definition at line 156 of file qxsdvalidatedxmlnodemodel.cpp.

{
    return m_internalModel->attributes(index);
}

baseUri()

QUrl XsdValidatedXmlNodeModel::baseUri ( const QXmlNodeModelIndex &  n ) const

virtual

Returns the base URI for the node whose index is n.

The caller guarantees that n is not null and that it belongs to a node in this node model.

The base URI of a node can be extracted using the fn:base-uri() function. The base URI is typically used for resolving relative URIs that appear in the node or its children. It is conformant to just return the document URI, although that might not properly reflect the underlying data.

This function maps to the dm:base-uri accessor, which returns a base URI according to the following:

• For document nodes, the base URI and the document URI are the same.

• For elements, the base URI is the URI appearing in the element's xml:base attribute, if present, or it is resolved to the parent element's base URI.

• Namespace nodes have no base URI.

• The base URI for a processing instruction, comment, attribute, or text node is the base URI of the node's parent element.

The implementation guarantees to return a valid QUrl, or a default constructed QUrl. If a node has no base URI, as in the case where a comment has no parent, a default constructed QUrl is returned.

compareOrder()

QXmlNodeModelIndex::DocumentOrder XsdValidatedXmlNodeModel::compareOrder ( const QXmlNodeModelIndex &  ni1, const QXmlNodeModelIndex &  ni2  ) const

virtual

This function returns the relative document order for the nodes indexed by ni1 and ni2.

It is used for the Is operator and for sorting nodes in document order.

The caller guarantees that ni1 and ni2 are not null and that both identify nodes in this node model.

If ni1 is identical to ni2, QXmlNodeModelIndex::Is is returned. If ni1 precedes ni2 in document order, QXmlNodeModelIndex::Precedes is returned. If ni1 follows ni2 in document order, QXmlNodeModelIndex::Follows is returned.

{
    return m_internalModel->compareOrder(index, otherIndex);
}

copyNodeTo()

void XsdValidatedXmlNodeModel::copyNodeTo ( const QXmlNodeModelIndex &  node, QAbstractXmlReceiver *const  receiver, const NodeCopySettings &  settings  ) const

virtual

Definition at line 146 of file qxsdvalidatedxmlnodemodel.cpp.

{
    return m_internalModel->copyNodeTo(index, receiver, settings);
}

documentUri()

QUrl XsdValidatedXmlNodeModel::documentUri ( const QXmlNodeModelIndex &  n ) const

virtual

Returns the document URI of n.

The document URI identifies the resource which is the document. For example, the document could be a regular file, e.g., file:/, or it could be the http:// URL of the location of a file. The document URI is used for resolving URIs and to simply know where the document is.

If the node model maps to a URI in a natural way, return that URI. Otherwise, return the company or product URI. The document URI can be any URI as long as its valid and absolute.

The caller guarantees that n is not null and that it belongs to this QAbstractXmlNodeModel.

This function maps to the dm:document-uri accessor, which returns a document URI according to the following:

• If n is a document node, return an absolute QUrl containing the document URI, or a default constructed QUrl. The latter signals that no document URI is available for the document node.

• For all other nodes, return a default constructed QUrl.

    return m_internalModel->documentUri(index);
}

elementById()

QXmlNodeModelIndex XsdValidatedXmlNodeModel::elementById ( const QXmlName &  id ) const

virtual

Returns the index of the element identified as id.

XQuery's id() function calls this function.

The node index returned will be the element node whose value is of type ID and equals id, or it will be the element node that has an attribute whose typed value is of type ID and equals id. If there is no such element, a default constructed QXmlNodeModelIndex instance is returned. The implementor guarantees that if the returned node index is not null, it identifies an element.

It is not sufficient for an attribute or element to merely be called id. Its value type must also be ID. However, the reserved name xml:id is sufficient.

In id, the namespace URI and the prefix are undefined, and the local name is the ID that should be looked up.

isDeepEqual()

bool XsdValidatedXmlNodeModel::isDeepEqual ( const QXmlNodeModelIndex &  n1, const QXmlNodeModelIndex &  n2  ) const

virtual

Determines whether ni1 is deep equal to ni2.

Warning

This function is not part of the public interface.

isDeepEqual() is defined as evaluating the expression fn:deep-equal($n1, $n2) where $n1 is ni1 and $n1 is ni2. This function is associative, meaning the same value is returned regardless of if isDeepEqual() is invoked with ni1 as first argument or second. It is guaranteed that ni1 and ni2 are nodes, as opposed to the definition of fn:deep-equal().

Returns true if ni1 is deep-equal to ni2, otherwise false

iterate()

QExplicitlySharedDataPointer< QAbstractXmlForwardIterator< QXmlNodeModelIndex > > XsdValidatedXmlNodeModel::iterate ( const QXmlNodeModelIndex &  ni, QXmlNodeModelIndex::Axis  axis  ) const

virtual

Performs navigation, starting from ni, by returning an QAbstractXmlForwardIterator that returns nodes the axis emanating from ni.

Warning

This function is not part of the public interface.

The implementation returns the nodes on the axis, without duplicates and in axis order. This means that if axis is a reverse axis, which is the case for the parent, ancestor, ancestor-or-self, preceding, and preceding-sibling, the nodes are delivered in reverse document order. Otherwise the nodes are delivered in document order.

The implementor guarantees that the nodes delivered for the axes are consistent with the XPath Data Model. This just implies common sense, e.g., The child axis for a comment node can't contain any children; a document node can't be a child of an element, etc. Attributes aren't considered children of an element, but are only available on AxisAttribute.

The value past in axis is not guaranteed based on what is used in a query. QtXmlPatterns may call this function arbitrarily with any value for axis. This is because QtXmlPatterns may rewrite queries to be more efficient, using axes in different ways from the original query.

QAbstractXmlNodeModel::Axis has a good overview of the axes and what they select.

The caller guarantees that ni is not null and that it belongs to this QAbstractXmlNodeModel instance.

Implementing iterate() can involve significant work, since it requires different iterators for all the axes used. In the worst case, it could require writing as many QAbstractXmlForwardIterator subclasses as there are axes, but the number can often be reduced with clever use of lists and template classes. It is better to use or subclass QSimpleXmlNodeModel, which makes it easier to write the node navigation code without loss of efficiency or flexibility.

kind()

QXmlNodeModelIndex::NodeKind XsdValidatedXmlNodeModel::kind ( const QXmlNodeModelIndex &  ni ) const

Returns a value indicating the kind of node identified by ni.

The caller guarantees that ni is not null and that it identifies a node in this node model. This function maps to the dm:node-kind() accessor.

name()

QXmlName XsdValidatedXmlNodeModel::name ( const QXmlNodeModelIndex &  ni ) const

virtual

Returns the name of ni.

The caller guarantees that ni is not null and that it belongs to this QAbstractXmlNodeModel.

If a node does not have a name, e.g., comment nodes, a null QXmlName is returned. QXmlNames must be created with the instance of QXmlQuery that is being used for evaluating queries using this QAbstractXmlNodeModel.

This function maps to the dm:node-name() accessor.

If ni is a processing instruction, a QXmlName is returned with the local name as the target name and the namespace URI and prefix both empty.

namespaceBindings()

QVector< QXmlName > XsdValidatedXmlNodeModel::namespaceBindings ( const QXmlNodeModelIndex &  n ) const

virtual

Returns the in-scope namespaces of n.

The caller guarantees that n is not null and that it belongs to this QAbstractXmlNodeModel.

This function corresponds to the dm:namespace-nodes accessor.

The returned vector of namespace declarations includes namespaces of the ancestors of n.

The caller guarantees that n is an Element that belongs to this QAbstractXmlNodeModel.

namespaceForPrefix()

QXmlName::NamespaceCode XsdValidatedXmlNodeModel::namespaceForPrefix ( const QXmlNodeModelIndex &  ni, const QXmlName::PrefixCode  prefix  ) const

virtual

Returns the namespace URI on ni that corresponds to prefix.

Warning

This function is not part of the public interface.

If prefix is StandardPrefixes::empty, the namespace URI for the default namespace is returned.

The default implementation use namespaceBindings(), in a straight forward manner.

If no namespace exists for prefix, NamespaceResolver::NoBinding is returned.

The caller guarantees to only call this function for element nodes.

    return m_internalModel->namespaceForPrefix(index, prefix);
}

nextFromSimpleAxis()

QXmlNodeModelIndex XsdValidatedXmlNodeModel::nextFromSimpleAxis ( SimpleAxis  axis, const QXmlNodeModelIndex &  origin  ) const

protectedvirtual

When QtXmlPatterns evaluate path expressions, it emulate them through a combination of calls with QSimpleXmlNodeModel::SimpleAxis values.

Therefore, the implementation of this function must return the node, if any, that appears on the axis emanating from the origin.

If no such node is available, a default constructed QXmlNodeModelIndex is returned.

QSimpleXmlNodeModel eliminates the need to handle redundant corner cases by guaranteeing that it will never ask for:

• Children or siblings for attributes.
• Children for comments, processing instructions, and text nodes.
• Siblings or parents for document nodes.

A typical implementation performs a switch on the value of axis:

QXmlNodeModelIndex MyTreeModel::nextFromSimpleAxis(SimpleAxis axis, const QXmlNodeModelIndex &origin) const
{
  // Convert the QXmlNodeModelIndex to a value that is specific to what we represent.
  const MyValue value = toMyValue(ni);

  switch(axis)
  {
      case Parent:
          return toNodeIndex(value.parent());
      case FirstChild:
      case PreviousSibling:
      case NextSibling:
          // and so on
  }
}

Implements QAbstractXmlNodeModel.

Definition at line 151 of file qxsdvalidatedxmlnodemodel.cpp.

{
    return m_internalModel->nextFromSimpleAxis(axis, origin);
}

nodesByIdref()

QVector< QXmlNodeModelIndex > XsdValidatedXmlNodeModel::nodesByIdref ( const QXmlName &  idref ) const

virtual

Returns the elements and/or attributes that have an IDREF value equal to idref.

XQuery's idref() function calls this function.

The implementor guarantees that the nodes identified by the returned indexes are elements or attributes.

It is not sufficient for an attribute or element to merely be called idref. It must also be of type IDREF. Elements must be typed as xs:IDREF or xs:IDREFS, or, in the case of attributes, as IDREF or IDREFS in the schema.

In idref, the namespace URI and the prefix are undefined, and the local name is the ID that should be looked up.

root()

QXmlNodeModelIndex XsdValidatedXmlNodeModel::root ( const QXmlNodeModelIndex &  n ) const

virtual

Returns the root node of the tree that contains the node whose index is n.

The caller guarantees that n is not null and that it identifies a node in this node model.

If n identifies a node that is a direct child of the root, parent() would return the same QXmlNodeModelIndex returned by this function.

stringValue()

QString XsdValidatedXmlNodeModel::stringValue ( const QXmlNodeModelIndex &  n ) const

virtual

Returns the string value for node n.

The caller guarantees that n is not null and that it belong to this QAbstractXmlNodeModel instance.

This function maps to the dm:string-value() accessor, which the specification completely specifies. Here's a summary:

• For processing instructions, the string value is the data section(excluding any whitespace appearing between the name and the data).

• For text nodes, the string value equals the text node.

• For comments, the content of the comment

• For elements, the concatenation of all text nodes that are descendants. Note, this is not only the children, but the childrens' childrens' text nodes, and so forth.

• For document nodes, the concatenation of all text nodes in the document.

QVariant XsdValidatedXmlNodeModel::typedValue ( const QXmlNodeModelIndex &  node ) const

virtual

Returns the typed value for node node.

The typed value is an atomic value, which an element or attribute contains.

The caller guarantees that node is either an element or an attribute. The implementor guarantees that the returned QVariant has a value which is supported in XQuery. It cannot be an arbitrary QVariant value. The implementor also guarantees that stringValue() returns a lexical representation of typedValue()(this is guaranteed by QSimpleXmlNodeModel::stringValue()).

If the return QVariant is a default constructed variant, it signals that node has no typed value.

Implements QAbstractXmlNodeModel.
