Constructors and Destructors

BuiltinNodeType()

template<const QXmlNodeModelIndex::NodeKind kind>

QPatternist::BuiltinNodeType< kind >::BuiltinNodeType ( )

protected

This constructor does nothing, but exists in order to make it impossible to instantiate this class from anywhere but from BuiltinTypes.

itemMatches()

template<const QXmlNodeModelIndex::NodeKind kind>

bool QPatternist::BuiltinNodeType< kind >::itemMatches ( const Item &  item ) const

virtual

Parameters

item	the item that is to be matched. This is guaranteed by the caller to never be null.

Reimplemented from QPatternist::AnyNodeType.

Definition at line 65 of file qbuiltinnodetype.cpp.

{
    Q_ASSERT(item);

    return item.isNode() &&

}

nodeKind()

template<const QXmlNodeModelIndex::NodeKind kind>

QXmlNodeModelIndex::NodeKind QPatternist::BuiltinNodeType< kind >::nodeKind ( ) const

virtual

Returns

the node kind this node ItemType tests for. If it matches any node, zero is returned.

Reimplemented from QPatternist::AnyNodeType.

Definition at line 130 of file qbuiltinnodetype.cpp.

{
    return kind;

patternPriority()

template<const QXmlNodeModelIndex::NodeKind kind>

xdtSuperType()

template<const QXmlNodeModelIndex::NodeKind kind>

ItemType::Ptr QPatternist::BuiltinNodeType< kind >::xdtSuperType ( ) const

virtual

Determines the type's parent type in the XPath Data Model hierarchy. For example, for the type xs:anyAtomicType, the super type in the XPath Data Model is item(), not xs:anySimpleType. SchemaType::xdtSuperType navigates the schema hierarchy.

See also

SchemaType::wxsSuperType()

Returns

the type's super type.

Reimplemented from QPatternist::AnyNodeType.

Definition at line 124 of file qbuiltinnodetype.cpp.

{
    return BuiltinTypes::node;
}

xdtTypeMatches()

template<const QXmlNodeModelIndex::NodeKind kind>

bool QPatternist::BuiltinNodeType< kind >::xdtTypeMatches ( const ItemType::Ptr &  other ) const

virtual

Returns true if other matches this type. That is, if other is equal to this type or a subtype of this type.

For instance this statements evaluates to true:

BuiltinTypes::xsAnyAtomicType->xdtTypeMatches(BuiltinTypes::xsString);

but this evaluates to false:

BuiltinTypes::attribute->xdtTypeMatches(BuiltinTypes::node);

Parameters

other

the other ItemType that is to be matched. This is guaranteed by the caller to never be null.

Reimplemented from QPatternist::AnyNodeType.

Definition at line 54 of file qbuiltinnodetype.cpp.

{
    if(!other->isNodeType())
        return false;

    return *static_cast<const BuiltinNodeType *>(other.data()) == *this
            ? true
            : xdtTypeMatches(other->xdtSuperType());
