Classes
struct	juce::Enumerated< Index, Value >
	Returned when dereferencing an EnumerateIterator. More...
class	juce::EnumerateIterator< Iter, Index >
	An iterator that wraps some other iterator, keeping track of the relative position of that iterator based on calls to arithmetic operators such as operator++(), operator--(), operator+(), and operator-(). More...
class	juce::IteratorPair< Begin, End >
	Wraps a pair of iterators, providing member begin() and end() functions that return those iterators. More...

Functions
template<typename Begin , typename End = Begin>
constexpr auto	juce::makeRange (Begin begin, End end)
	Given two iterators "begin" and "end", returns an IteratorPair with a member begin() and end() function.
template<typename Range , typename Index = detail::withAdlSize::AdlSignedSize<Range>>
constexpr auto	juce::enumerate (Range &&range, Index startingValue={})
	Given a range and an optional starting offset, returns an IteratorPair that holds EnumerateIterators wrapping the begin() and end() of the range.

Class Documentation

juce::Enumerated

struct juce::Enumerated

template<typename Index, typename Value>
struct juce::Enumerated< Index, Value >

Returned when dereferencing an EnumerateIterator.

Allows querying the index associated with an element, along with a reference to the element itself.

You should never need to construct an instance of this type yourself. Instead, use the enumerate() function to construct a range that can be enumerated.
