copyBackward()

template<class BidirIt1 , class BidirIt2 >

BidirIt2 Ponca::internal::copyBackward	(	BidirIt1	first,
		BidirIt1	last,
		BidirIt2	d_last
	)

Copies the elements from the range [first, last) to another range ending at d_last.

The elements are copied in reverse order (the last element is copied first), but their relative order is preserved.

Warning

The behavior is undefined if d_last is within (first, last].

Template Parameters

BidirIt1	must meet the requirements of LegacyBidirectionalIterator
BidirIt2	must meet the requirements of LegacyBidirectionalIterator

Parameters

first	Iterator defining the beginning of the range of elements to copy from (the source)
last	Iterator defining the end of the range of elements to copy from (the source)
d_last	The end of the destination range

fill()

template<class ForwardIt , class T = typename std::iterator_traits<ForwardIt>::value_type>

void Ponca::internal::fill	(	ForwardIt	first,
		ForwardIt	last,
		const T &	value
	)

Assigns the given value to all elements in the range [first, last).

Note

If value is not writable to first, the program is ill-formed.

Template Parameters

ForwardIt	ForwardIt must meet the requirements of LegacyForwardIterator
T	The type of the value to be assigned

Parameters

first	Iterator defining the beginning of the range of elements to modify
last	Iterator defining the end of the range of elements to modify
value	the value to be assigned

ForwardIt Ponca::internal::upperBound	(	ForwardIt	first,
		ForwardIt	last,
		const T &	value,
		Compare	comp
	)

Searches for the first element in the partitioned range [first, last) which is ordered after value.

Template Parameters

ForwardIt	Must meet the requirements of LegacyForwardIterator
Compare	Must meet the requirements of BinaryPredicate. It is not required to satisfy Compare.

Parameters

first	Iterator defining the beginning of the range of elements to examine
last	Iterator defining the end of the range of elements to examine
value	Value to compare the elements to
comp	binary predicate which returns True if the first argument is ordered before the second.

Returns

Iterator to the first element of the range [first, last) ordered after value, or last if no such element is found.
