Function Documentation

find_index()

template<typename Container >

int find_index	(	Container const &	container,
		typename Container::const_reference	item
	)

Helper function to get the index of an item Consider using std::set, std::unordered_set or std::flat_set in new code.

Parameters

container	A reference to the container to be searched.
item	Reference to the item to be search for

Returns

Index of element if found, otherwise -1

include()

template<typename Container >

bool include ( Container &  container, typename Container::const_reference &  item  )

inline

Helper function to append an item to a container if it is not already contained.

The container must have a emplace_back function. Consider using std::set, std::unordered_set or std::flat_set in new code.

Parameters

container	A reference to the container to be extended
item	Reference to the item to be copy-constructed if not found

Returns

Whether the item was already present

Slide()

template<typename TIter >

auto Slide	(	TIter	first,
		TIter	last,
		TIter	position
	)		-> std::pair<TIter, TIter>

Move elements between first and last to a new position, rotating elements in between as necessary.

Parameters

first	Iterator to first element to move.
last	Iterator to (end-of) last element to move.
position	Iterator to where range should be moved to.

Returns

Iterators to first and last after being moved.
