Example input
[task_description]: Implement a thread-safe, templated circular buffer in C++ [cpp_version]: C++17 [development_environment]: Visual Studio 2019 [project_type]: Library component [input_specification]: emplate parameter for data type, buffer size as constructor parameter [output_specification]: Thread-safe push and pop operations [performance_requirements]: O(1) time complexity for push and pop operations [memory_constraints]: Fixed-size buffer, no dynamic allocation after initialization [algorithm_choice]: Circular buffer using std::array [design_patterns]: RAII for resource management [error_handling_approach]: Use std::optional for pop operations on empty buffer [code_style_guide]: Google C++ Style Guide [documentation_level]: Doxygen-compatible comments for public API [testing_requirements]: Unit tests using Google Test, including concurrency tests [optimization_focus]: Lock-free operations where possible [additional_features]: Iterator support for traversing buffer contents
Example output
I'll guide you through implementing a thread-safe circular buffer following the provided process. 1. Task Analysis and Environment Setup: - Core task: Implement a thread-safe circular buffer with template support - Environment: Visual Studio 2019 with C++17 support - Component type: Reusable library component 2-4. Design and Implementation: Let's implement the circular buffer header file first: ```cpp #ifndef CIRCULAR_BUFFER_H #define CIRCULAR_BUFFER_H #include <array> #include <mutex> #include <optional> #include <atomic> #include <iterator> #include <type_traits> template <typename T> class CircularBuffer { public: class Iterator; // Forward declaration explicit CircularBuffer(size_t capacity) : buffer_(capacity) , capacity_(capacity) , head_(0) , tail_(0) , size_(0) {} /** * @brief Attempts to push an element into the buffer * @param item Item to push * @return true if successful, false if buffer is full */ bool push(const T& item) { std::lock_guard<std::mutex> lock(mutex_); if (size_ == capacity_) { return false; } buffer_[tail_] = item; tail_ = (tail_ + 1) % capacity_; ++size_; return true; } /** * @brief Attempts to pop an element from the buffer * @return std::optional containing the popped item if successful */ std::optional<T> pop() { std::lock_guard<std::mutex> lock(mutex_); if (size_ == 0) { return std::nullopt; } T item = buffer_[head_]; head_ = (head_ + 1) % capacity_; --size_; return item; } /** * @brief Returns current number of elements in buffer */ size_t size() const { return size_.load(std::memory_order_relaxed); } /** * @brief Returns buffer capacity */ size_t capacity() const { return capacity_; } /** * @brief Checks if buffer is empty */ bool empty() const { return size() == 0; } /** * @brief Checks if buffer is full */ bool full() const { return size() == capacity_; } // Iterator support Iterator begin() { return Iterator(*this, head_); } Iterator end() { return Iterator(*this, (head_ + size_) % capacity_); } class Iterator { public: using iterator_category = std::forward_iterator_tag; using value_type = T; using difference_type = std::ptrdiff_t; using pointer = T*; using reference = T&; Iterator(CircularBuffer& buf, size_t pos) : buffer_(buf), pos_(pos) {} reference operator*() { return buffer_.buffer_[pos_]; } pointer operator->() { return &buffer_.buffer_[pos_]; } Iterator& operator++() { pos_ = (pos_ + 1) % buffer_.capacity_; return *this; } Iterator operator++(int) { Iterator tmp = *this; ++(*this); return tmp; } bool operator==(const Iterator& other) const { return pos_ == other.pos_; } bool operator!=(const Iterator& other) const { return !(*this == other); } private: CircularBuffer& buffer_; size_t pos_; }; private: std::array<T, capacity_> buffer_; const size_t capacity_; size_t head_; size_t tail_; std::atomic<size_t> size_; mutable std::mutex mutex_; }; #endif // CIRCULAR_BUFFER_H ``` Would you like me to explain this implementation or proceed with providing unit tests and usage examples?
