XmlAtomicValue

XmlAtomicValue class

Represents the typed value of a validated XML element or attribute. The XmlAtomicValue class cannot be inherited.

class XmlAtomicValue : public System::Xml::XPath::XPathItem

Methods

MethodDescription
SharedPtr<XmlAtomicValue> Clone()Returns a copy of this XmlAtomicValue object.
virtual bool Equals(ptr)Compares objects using C# Object.Equals semantics.
static std::enable_if<IsSmartPtr<T1>::value&&IsSmartPtr<T2>::value, bool>::type Equals(T1 const&, T2 const&)Compares reference type objects in C# style.
static std::enable_if<!IsSmartPtr<T1>::value&&!IsSmartPtr<T2>::value, bool>::type Equals(T1 const&, T2 const&)Compares value type objects in C# style.
static bool Equals(float const&, float const&)Emulates C#-style floating point comparison where two NaNs are considered equal even though according to IEC 60559:1989 NaN is not equal to any value, including NaN.
static bool Equals(double const&, double const&)Emulates C#-style floating point comparison where two NaNs are considered equal even though according to IEC 60559:1989 NaN is not equal to any value, including NaN.
virtual bool FastCast(const Details::FastRttiBase&, void **) constFor internal purposes only.
bool get_IsNode() overrideReturns a value indicating whether the validated XML element or attribute is an XPath node or an atomic value.
SharedPtr<Object> get_TypedValue() overrideReturns the current validated XML element or attribute as a boxed object of the most appropriate type according to its schema type.
String get_Value() overrideReturns the String value of the validated XML element or attribute.
bool get_ValueAsBoolean() overrideReturns the validated XML element or attribute’s value as a Boolean.
DateTime get_ValueAsDateTime() overrideReturns the validated XML element or attribute’s value as a DateTime.
double get_ValueAsDouble() overrideReturns the validated XML element or attribute’s value as a Double.
int32_t get_ValueAsInt() overrideReturns the validated XML element or attribute’s value as an Int32.
int64_t get_ValueAsLong() overrideReturns the validated XML element or attribute’s value as an Int64.
TypeInfo get_ValueType() overrideReturns the type of the validated XML element or attribute.
SharedPtr<XmlSchemaType> get_XmlType() overrideReturns the XmlSchemaType for the validated XML element or attribute.
Detail::SmartPtrCounter * GetCounter()Gets reference counter data structure associated with the object.
virtual int32_t GetHashCode() constAnalog of C# Object.GetHashCode() method. Enables hashing of custom objects.
virtual const TypeInfo& GetType() constGets actual type of object. Analog of C# System.Object.GetType() call.
virtual bool Is(const TypeInfo&) constCheck if object represents an instance of type described by targetType. Analog of C# ‘is’ operator.
void Lock()Implements C# lock() statement locking. Call directly or use LockContext sentry object.
virtual ptr MemberwiseClone() constAnalog of C# Object.MemberwiseClone() method. Enables cloning custom types.
Object()Creates object. Initializes all internal data structures.
Object(Object const&)Copy constructor. Doesn’t copy anything, really, just initializes new object and enables copy constructing subclasses.
Object& operator=(Object const&)Assignment operator. Doesn’t copy anything, really, just initializes new object and enables copy constructing subclasses.
static bool ReferenceEquals(ptr const&, ptr const&)Compares objects by reference.
static std::enable_if<!IsSmartPtr<T>::value, bool>::type ReferenceEquals(T const&, T const&)Compares objects by reference.
static std::enable_if<!IsSmartPtr<T>::value, bool>::type ReferenceEquals(T const&, std::nullptr_t)Reference-compares value type object with nullptr.
bool ReferenceEquals(String const&, std::nullptr_t)Specialization of Object::ReferenceEquals for case of string and nullptr.
bool ReferenceEquals(String const&, String const&)Specialization of Object::ReferenceEquals for case of strings.
int RemovedSharedRefs(int)Decreases shared reference count by specified value.
virtual void SetTemplateWeakPtr(uint32_t)Set n’th template argument a weak pointer (rather than shared). Allows switching pointers in containers to weak mode.
int SharedCount() constGets current value of shared reference counter.
Object * SharedRefAdded()Increments shared reference count. Shouldn’t be called directly; instead, use smart pointers or ThisProtector.
int SharedRefRemovedSafe()Decrements and returns shared reference count. Shouldn’t be called directly; instead, use smart pointers or ThisProtector.
String ToString() const overrideReturns the String value of the validated XML element or attribute.
static const TypeInfo& Type()Implements C# typeof(System.Object) construct.
void Unlock()Implements C# lock() statement unlocking. Call directly or use LockContext sentry object.
SharedPtr<Object> ValueAs(const TypeInfo&, SharedPtr<IXmlNamespaceResolver>) overrideReturns the validated XML element or attribute’s value as the type specified using the IXmlNamespaceResolver object specified to resolve namespace prefixes.
virtual SharedPtr<Object> ValueAs(const TypeInfo&)Returns the item’s value as the specified type.
Detail::SmartPtrCounter * WeakRefAdded()Increments weak reference count. Shouldn’t be called directly; instead, use smart pointers or ThisProtector.
void WeakRefRemoved()Decrements weak reference count. Shouldn’t be called directly; instead, use smart pointers or ThisProtector.
virtual ~Object()Destroys object. Frees all internal data structures.

Typedefs

TypedefDescription
PtrAn alias for shared pointer to an instance of this class.

Remarks

Objects of this class should only be allocated using System::MakeObject() function. Never create instances of this type on stack or using operator new, as it will result in runtime errors and/or assertion faults. Always wrap this class into System::SmartPtr pointer and use this pointer to pass it to functions as argument.
