Functions

atomizedType()

ItemType::Ptr AnyNodeType::atomizedType ( ) const

virtual

See also

XQuery 1.0 and XPath 2.0 Data Model, G.15 dm:typed-value Accessor

Implements QPatternist::ItemType.

Reimplemented in QPatternist::BuiltinNodeType< kind >, and QPatternist::AbstractNodeTest.

Definition at line 61 of file qanynodetype.cpp.

{
    return BuiltinTypes::xsAnyAtomicType;
}

displayName()

QString AnyNodeType::displayName ( const NamePool::Ptr &  np ) const

virtual

Returns

a string representing the type. Used for diagnostic purposes. For a type whose name is a QName, a lexical representation should be returned with the prefix being a conventional one. Examples of a display names are "item()" and "xs:nonPositiveInteger".

Implements QPatternist::ItemType.

Reimplemented in QPatternist::BuiltinNodeType< kind >, QPatternist::LocalNameTest, QPatternist::NamespaceNameTest, and QPatternist::QNameTest.

Definition at line 66 of file qanynodetype.cpp.

{
    return QLatin1String("node()");
}

isAtomicType()

bool AnyNodeType::isAtomicType ( ) const

virtual

Implements QPatternist::ItemType.

Definition at line 81 of file qanynodetype.cpp.

{
    return false;
}

isNodeType()

bool AnyNodeType::isNodeType ( ) const

virtual

Implements QPatternist::ItemType.

Definition at line 76 of file qanynodetype.cpp.

{
    return true;
}

itemMatches()

bool AnyNodeType::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.

Implements QPatternist::ItemType.

Reimplemented in QPatternist::LocalNameTest, QPatternist::NamespaceNameTest, QPatternist::QNameTest, QPatternist::XSLTNodeTest, and QPatternist::BuiltinNodeType< kind >.

Definition at line 56 of file qanynodetype.cpp.

{
    return item.isNode();
}

nodeKind()

QXmlNodeModelIndex::NodeKind AnyNodeType::nodeKind ( ) const

virtual

Returns

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

Reimplemented in QPatternist::BuiltinNodeType< kind >.

Definition at line 86 of file qanynodetype.cpp.

{
    /* node() is an abstract type, so we don't have a value for it in
     * QXmlNodeModelIndex::NodeKind. */
    return QXmlNodeModelIndex::NodeKind(0);
}

patternPriority()

PatternPriority AnyNodeType::patternPriority ( ) const

virtual

Reimplemented in QPatternist::BuiltinNodeType< kind >, QPatternist::QNameTest, QPatternist::LocalNameTest, and QPatternist::NamespaceNameTest.

Definition at line 93 of file qanynodetype.cpp.

{
    return -0.5;
}

xdtSuperType()

ItemType::Ptr AnyNodeType::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.

Implements QPatternist::ItemType.

Reimplemented in QPatternist::BuiltinNodeType< kind >, QPatternist::XSLTNodeTest, and QPatternist::AbstractNodeTest.

Definition at line 71 of file qanynodetype.cpp.

{
    return BuiltinTypes::item;
}

xdtTypeMatches()

bool AnyNodeType::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.

Implements QPatternist::ItemType.

Reimplemented in QPatternist::XSLTNodeTest, QPatternist::BuiltinNodeType< kind >, and QPatternist::AbstractNodeTest.

Definition at line 51 of file qanynodetype.cpp.

{
    return other->isNodeType();
}
