Detailed Description

template<typename Container, typename Element>
class System::Collections::Generic::BaseEnumerator< Container, Element >

Enumerator definition to wrap STL-styled types for C#-styled usage. Makes no assertions on container structure except for existance of sequental iterator. Uses begin() and end() functions. 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.

Template Parameters
ContainerSTL-styled container type.
ElementElement type.

Constructor & Destructor Documentation

◆ BaseEnumerator()

template<typename Container, typename Element>
System::Collections::Generic::BaseEnumerator< Container, Element >::BaseEnumerator ( Object::ptr  owner,
Container &  cont 
)
inline

Initializes iterator.

Parameters
ownerPointer to owner container.
contActual container implementation reference.

Member Function Documentation

◆ IsValid()

template<typename Container, typename Element>
bool System::Collections::Generic::BaseEnumerator< Container, Element >::IsValid ( ) const
inline

Checks whether MoveNext() was called and end was not reached.

Returns
false if MoveNext() was not called at all or container end is hit; true otherwise.

◆ MoveNext()

template<typename Container, typename Element>
bool System::Collections::Generic::BaseEnumerator< Container, Element >::MoveNext ( )
inlineoverridevirtual

Enumerator-style increment.

Returns
true if enumerator points to valid element, false if container end is hit.

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

◆ Reset()

template<typename Container, typename Element>
void System::Collections::Generic::BaseEnumerator< Container, Element >::Reset ( )
inlineoverridevirtual

Resets enumerator to allow re-enumerating elements.

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