C++ custom STL container memory allocator (map, set, vector, string, unordered_map, unordered_set)

Notice: When using the C++ 11/14 standard, you should comment the following code and restore the above commented code, that is, set the compiler option standard to: -std=cxx1z, -std=cxx2a. // C++17…cxx1z //template <class _Iter> //constexpr void* _Voidify_iter(_Iter _It) noexcept { // if constexpr (std::is_pointer<_Iter>::value) { // return const_cast<void*>(static_cast<const volatile void*>(_It)); // } // else { […]

c++ vector container

1. Introduction Vector is a Sequence Container that encapsulates a dynamically sized array. Like any other type of container, it can store various types of objects. You can simply think of a vector as a dynamic array that can store any type. 1.1 The difference between vector and ordinary array Ordinary arrays are static, the […]

How to transform a three-dimensional vector based on the A coordinate system to the B coordinate system in ROS?

Abstract In ROS, the rotation quaternion rot from the A coordinate system to the B coordinate system is obtained through the tf.TransformListener.lookupTransform method, and the quaternion coordinate representation in the new coordinate system is obtained through the quaternion_multiply function. Based on this, this blog provides standard code templates and application examples for transforming a three-dimensional […]
