IEnumerator

IEnumerator class

Interface of enumerator which can be used to iterate through some elements. Objects of this class should only be allocated using System::MakeObject() function. Never create instance 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.

class IEnumerator : public virtual System::IDisposable,
                    public virtual System::Object

Template parameters

Parameter	Description
T	Element type.

Methods

Method	Description

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.
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 **) const	For internal purposes only.
virtual const SharedPtr<System::Object>& get_Current() const	Gets current element.
Detail::SmartPtrCounter * GetCounter()	Gets reference counter data structure associated with the object.
Detail::SmartPtrCounter * GetCounter()	Gets reference counter data structure associated with the object.
virtual int32_t GetHashCode() const	Analog of C# Object.GetHashCode() method. Enables hashing of custom objects.
virtual const TypeInfo& GetType() const	Gets actual type of object. Analog of C# System.Object.GetType() call.
virtual bool Is(const TypeInfo&) const	Check if object represents an instance of type described by targetType. Analog of C# ‘is’ operator.

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.
static bool ReferenceEquals(ptr const&, ptr 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.
int RemovedSharedRefs(int)	Decreases shared reference count by specified value.
virtual void Reset()	Resets enumerator to position before first element.
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() const	Gets current value of shared reference counter.
int SharedCount() const	Gets current value of shared reference counter.
Object * SharedRefAdded()	Increments shared reference count. Shouldn’t be called directly; instead, use smart pointers or ThisProtector.
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.
