Detailed Description

template<typename T>
class System::Array< T >::Enumerator

Implements IEnumerator interface that enables enumeration of elements of an Array object. 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.

Constructor & Destructor Documentation

◆ Enumerator()

template<typename T >
System::Array< T >::Enumerator::Enumerator ( const SharedPtr< Array< T >> &  arr)
inline

Constructs a new Enumerator object that represents the specified array.

Parameters
arrA shared pointer to the Array object

◆ ~Enumerator()

template<typename T >
virtual System::Array< T >::Enumerator::~Enumerator ( )
inlinevirtual

Destructor.

Member Function Documentation

◆ get_Current()

template<typename T >
virtual T System::Array< T >::Enumerator::get_Current ( )
inlineoverridevirtual

Returns a copy of the current element.

Implements System::Collections::Generic::IEnumerator< T >.

◆ MoveNext()

template<typename T >
virtual bool System::Array< T >::Enumerator::MoveNext ( )
inlineoverridevirtual

Checks if the current element's index does not point to the last element in the array and advances it if id does not.

Returns
True if the current element's index did not point to the last element in the array before it was advanced, othrewise - false

Implements System::Collections::Generic::IEnumerator< T >.

◆ Reset()

template<typename T >
virtual void System::Array< T >::Enumerator::Reset ( )
inlineoverridevirtual

Resets the current element's index.

Reimplemented from System::Collections::Generic::IEnumerator< T >.
