Functions

◆ accept() [1/2]

AtomicTypeVisitorResult::Ptr NumericType::accept	(	const AtomicTypeVisitor::Ptr &	visitor,
		const SourceLocationReflection * const
	)		const

virtual

NumericType cannot be visited. This function is only implemented to satisfy the abstract super class's interface.

Returns: always a null pointer

Definition at line 114 of file qnumerictype.cpp.

 {
     return AtomicTypeVisitorResult::Ptr();
 }

◆ accept() [2/2]

AtomicTypeVisitorResult::Ptr NumericType::accept	(	const ParameterizedAtomicTypeVisitor::Ptr &	visitor,
		const qint16	op,
		const SourceLocationReflection * const
	)		const

virtual

NumericType cannot be visited. This function is only implemented to satisfy the abstract super class's interface.

Returns: always a null pointer

Implements QPatternist::AtomicType.

Definition at line 120 of file qnumerictype.cpp.

 {
     return AtomicTypeVisitorResult::Ptr();
 }

◆ atomizedType()

ItemType::Ptr NumericType::atomizedType ( ) const

virtual

Returns: null. It makes no sense to atomize the abstract type fs:numeric.

Reimplemented from QPatternist::AtomicType.

Definition at line 109 of file qnumerictype.cpp.

 {
     return AtomicType::Ptr();
 }

◆ casterLocator()

AtomicCasterLocator::Ptr NumericType::casterLocator ( ) const

virtual

The type fs:numeric is an abstract type which therefore cannot be involved in casting. Hence, this function returns null. This function is only implemented to satisfy the abstract super class's interface.

Returns: always a null pointer

Implements QPatternist::AtomicType.

Definition at line 137 of file qnumerictype.cpp.

 {
     return AtomicCasterLocator::Ptr();
 }

◆ comparatorLocator()

AtomicComparatorLocator::Ptr NumericType::comparatorLocator ( ) const

virtual

The type fs:numeric is an abstract type which therefore cannot be involved in comparisons. Hence, this function returns null. This function is only implemented to satisfy the abstract super class's interface.

Returns: always a null pointer

Implements QPatternist::AtomicType.

Definition at line 127 of file qnumerictype.cpp.

 {
     return AtomicComparatorLocator::Ptr();
 }

◆ displayName()

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

virtual

Returns: always "numeric". That is, no namespace prefix

Reimplemented from QPatternist::AtomicType.

Definition at line 79 of file qnumerictype.cpp.

 {
     return QLatin1String("numeric");
 }

◆ isAbstract()

bool NumericType::isAbstract ( ) const

virtual

Returns: always true

Reimplemented from QPatternist::AnyType.

Definition at line 94 of file qnumerictype.cpp.

 {
     return true;
 }

◆ isAtomicType()

bool NumericType::isAtomicType ( ) const

virtual

Returns: always true

Reimplemented from QPatternist::AtomicType.

Definition at line 104 of file qnumerictype.cpp.

 {
     return true;
 }

◆ isNodeType()

bool NumericType::isNodeType ( ) const

virtual

Returns: always false

Reimplemented from QPatternist::AtomicType.

Definition at line 99 of file qnumerictype.cpp.

 {
     return false;
 }

◆ itemMatches()

bool NumericType::itemMatches ( const Item & item ) const

virtual

Implements a generic algorithm which relies on wxsTypeMatches().

Returns: true depending on if item is an atomic type, and that AtomicValue::itemType()'s SequenceType::itemType() matches this type.

Reimplemented from QPatternist::AtomicType.

Definition at line 61 of file qnumerictype.cpp.

 {
     if(item.isNode())
         return false;
 
     return BuiltinTypes::xsDouble->itemMatches(item)    ||
            BuiltinTypes::xsDecimal->itemMatches(item)   ||
            BuiltinTypes::xsFloat->itemMatches(item);
 }

◆ mathematicianLocator()

AtomicMathematicianLocator::Ptr NumericType::mathematicianLocator ( ) const

virtual

The type fs:numeric is an abstract type which therefore cannot be involved in arithmetics. Hence, this function returns null. This function is only implemented to satisfy the abstract super class's interface.

Returns: always a null pointer

Implements QPatternist::AtomicType.

Definition at line 132 of file qnumerictype.cpp.

 {
     return AtomicMathematicianLocator::Ptr();
 }

◆ wxsSuperType()

SchemaType::Ptr NumericType::wxsSuperType ( ) const

virtual

Returns: always xs:anyAtomicType

Reimplemented from QPatternist::AnySimpleType.

Definition at line 84 of file qnumerictype.cpp.

 {
     return BuiltinTypes::xsAnyAtomicType;
 }

◆ xdtSuperType()

ItemType::Ptr NumericType::xdtSuperType ( ) const

virtual

Returns: always xs:anyAtomicType

Implements QPatternist::ItemType.

Definition at line 89 of file qnumerictype.cpp.

 {
     return BuiltinTypes::xsAnyAtomicType;
 }

◆ xdtTypeMatches()

bool NumericType::xdtTypeMatches ( const ItemType::Ptr & other ) const

virtual

Determines whether other is equal to this type, or is a sub-type of this type.

The implementation is generic, relying on operator==() and xdtSuperType().

Reimplemented from QPatternist::AtomicType.

Definition at line 71 of file qnumerictype.cpp.

 {
     return BuiltinTypes::xsDouble->xdtTypeMatches(t)    ||
            BuiltinTypes::xsDecimal->xdtTypeMatches(t)   ||
            BuiltinTypes::xsFloat->xdtTypeMatches(t)     ||
            *t == *this; /* If it's NumericType */
 }
