Detailed Description

This is a terminal operator.

Function Documentation

all()

template<typename Pred >

auto coveo::linq::all

(

const Pred &

pred

)

-> detail::all_impl<Pred>

Scans a sequence and calls a predicate with each element. The predicate must return true if the element satisfies the predicate. The final result will indicate if all elements satisfy the predicate.

Works on empty sequences (returns true in such a case).

Use like this:

const int NUMS = { 42, 23, 66 };

using namespace coveo::linq;
bool all_big = from(NUMS)
             | all([](int i) { return i >= 10; });
bool all_odd = from(NUMS)
             | all([](int i) { return i % 2 != 0; });
// all_big == true
// all_odd == false

Parameters

pred	Predicate to satisfy.

Returns

(Once applied) true if all elements in sequence satisfy pred.
