О чём код?
#include "Tutorial.h" void Vector1() { /// .`Vector` basics /// `Vector` is the basic container of U++. It is the random access container similar to /// `std::vector` with one important performance related difference: There are rules for /// elements of `Vector` that allow its implementation to move elements in memory using /// plain `memcpy`/`memmove` ("Moveable" concept). /// Anyway, for now let us start with simple `Vector` of `int`s: Vector<int> v; /// You can add elements to the Vector as parameters of the Add method v.Add(1); v.Add(2); DUMP(v); /// Alternative and very important possibility for U++ containers is 'in-place creation'. /// In this case, parameter-less Add returns a reference to a new element in `Vector`: v.Add() = 3; DUMP(v); /// You can also use `operator<<` v << 4 << 5; DUMP(v); /// `Vector` also supports initializer lists: v.Append({ 6, 7 }); DUMP(v); /// To iterate `Vector` you can use indices: for(int i = 0; i < v.GetCount(); i++) LOG(v[i]); /// begin/end interface: for(auto q = v.begin(), e = v.end(); q != e; q++) LOG(*q); /// C++11 range-for syntax: for(const auto& q : v) LOG(q); /// }
