Detailed Description

The zip operator scans two source sequences and and passes elements with the same index to a result selector, then produces a sequence containing the results returned by that selector.

Function Documentation

zip()

template<typename Seq2 , typename ResultSelector >

auto coveo::linq::zip	(	Seq2 &&	seq2,
		ResultSelector &&	result_sel
	)		-> detail::zip_impl<Seq2, ResultSelector>

Scans two source sequences and calls the provided result selector with elements of the two sequences that have the same index. Then, produces a sequence of the results returned by that selector. The resulting sequence will be as long as the shortest of the two input sequences.

Use like this:

const int ONE[] = { 42, 23, 66, 11, 7 };
const int TWO[] = { 8, 21, 90, 4 };

using namespace coveo::linq;
auto seq = from(ONE)
         | zip(TWO, [](int i, int j) { return i + j; });
// seq = { 50, 44, 156, 15 }

Parameters

seq2	Second sequence to scan. The first sequence is the one to which the operator is applied, e.g. the one passed to coveo::linq::from().
result_sel	Selector used to "zip" two corresponding sequence elements.

Returns

(Once applied) Sequence containing zipped elements from the two sequences.
