iteratorAdvance()

template<class ITER>

ITER MissingETBase::Container::iteratorAdvance	(	ITER	iter,
		size_t	step )

Advance an iterator by a number of steps.

Returns

Advanced iterator.

Template Parameters

ITER	iterator type.

Note

ITER::operator+(size_t) must be defined.

Parameters

[in]	iter	starting iterator
[in]	step	number of steps to advance

Warning

There is no control on the number of steps. The resulting iterator maybe invalid, except if ITER has a protection build in.

{ ITER fIter(iter); std::advance(iter,step); return fIter; }

iteratorDiff()

template<class ITER>

size_t MissingETBase::Container::iteratorDiff	(	ITER	first,
		ITER	last )

Difference (number of steps) between two iterators.

Returns

Number of steps from first to last iterator.

Template Parameters

ITER	iterator type.

Note

ITER::operator-(const ITER&) must be defined with an integer return value >= 0.

Parameters

[in]	first	first iterator
[in]	last	last iterator

Note

first needs to be identical to last, or precede it. Otherwise the return value may be undefined.

{ return (size_t)(std::distance(first,last)); }
