Function Documentation

template<typename T_>

std::size_t paludis::capped_distance	(	T_	a,
		const T_ &	b,
		unsigned	n
	)			[inline]

Return the distance from a to b, except if it is greater than n, in which case return n instead.

template<typename Iter_>

IndirectIterator< Iter_ > paludis::indirect_iterator

(

const Iter_ &

t

)

[inline]

Construct an IndirectIterator from another iterator.

template<typename T_>

T_ paludis::next	(	const T_ &	i,
		const int &	n
	)			[inline]

Return a new iterator advanced by a distance of n.

template<typename T_>

T_ paludis::next

(

const T_ &

i

)

[inline]

Return a new iterator pointing to the item after i.

template<typename T_>

T_ paludis::previous

(

const T_ &

i

)

[inline]

Return a new iterator pointing to the item before i.
