Windows

MacOS

Linux

References

Module	Core

Include	#include "Containers/Array.h"

Syntax

template<typename ContainerType, typename ElementType, typename SizeType>
class TIndexedContainerIterator

Remarks

Generic iterator which can operate on types that expose the following:

A type called ElementType representing the contained type.
A method SizeType Num() const that returns the number of items in the container.
A method bool IsValidIndex(SizeType index) which returns whether a given index is valid in the container.
A method T& operator[](SizeType index) which returns a reference to a contained object by index.
A method void RemoveAt(SizeType index) which removes the element at index

Constructors

	Name	Description
	TIndexedContainerIterator ( ContainerType& InContainer, SizeType StartIndex )

Functions

	Name	Description
SizeType	GetIndex()	Returns an index to the current element.
void	RemoveCurrent()	Removes current element in array.
void	Reset()	Resets the iterator to the first element.
void	SetToEnd()	Sets iterator to the last element.

Operators

	Name	Description
TIndexedCont...	operator- ( SizeType Offset )
TIndexedCont...	operator--()	Moves iterator to the previous element in the container.
TIndexedCont...	operator-- ( int )
	operator bool()	Conversion to "bool" returning true if the iterator has not reached the last element.
ElementType ...	operator*()
TIndexedCont...	operator+ ( SizeType Offset )
TIndexedCont...	operator++ ( int )
TIndexedCont...	operator++()	Advances iterator to the next element in the container.
TIndexedCont...	operator+= ( SizeType Offset )	Iterator arithmetic support
TIndexedCont...	operator-= ( SizeType Offset )
ElementType ...	operator->()
