forEachPair()

template<typename FwIter , typename Func >

void lanelet::helper::forEachPair	(	FwIter	first,
		FwIter	end,
		Func	f
	)

apply a function for each pair of adjacent elements in a range

Parameters

first	first element in range
end	past-the-end iterator
f	function/lambda to apply (defines operator())

This is useful for iterating over a the segments in a LineString.

forEachPairUntil()

template<typename FwIter , typename Func >

FwIter lanelet::helper::forEachPairUntil	(	FwIter	first,
		FwIter	end,
		Func	f
	)

Apply a function of all pairs in a sequenc in sorted order until a predicate returns true.

Parameters

first	begin of the range to iterate over
end	end of the range to iterate over
f	function returning something convertible to bool. If the result is true, the iteration is stopped

Returns

Iterator to the first element of the pair that returned true or end

Works similar to forEachPair but stops if f returns true. Useful for implementing a search on segments.
