- Rename D3D12Enum.h to D3D12Enums.h for naming consistency - Fix OpenGL unit test GLAD initialization by using gladLoadGL() instead of gladLoadGLLoader(wglGetProcAddress) for fallback support - Migrate remaining tests to use gtest_discover_tests for granular test discovery (math, core, containers, memory, threading, debug, components, scene, resources, input, opengl) - Remove obsolete TEST_RESOURCES_DIR and copy_directory commands from OpenGL unit test CMakeLists (minimal/Res doesn't exist) - Update TEST_SPEC.md with performance metrics and per-module build/test commands for faster development workflow - Update CMake path references to use lowercase paths

# Mutex::try_lock
|
||
|
||
```cpp
|
||
bool try_lock() const;
|
||
```
|
||
|
||
尝试获取互斥锁(非阻塞,const 版本)。如果锁可用则立即获取并返回 `true`,否则立即返回 `false` 而不阻塞。
|
||
|
||
该方法是 `std::lockable` 接口的实现。
|
||
|
||
**参数:** 无
|
||
|
||
**返回:** `bool` - 获取成功返回 `true`,锁不可用返回 `false`
|
||
|
||
**线程安全:** ✅
|
||
|
||
**复杂度:** O(1)
|
||
|
||
**示例:**
|
||
|
||
```cpp
|
||
#include "XCEngine/Threading/Mutex.h"
|
||
#include <iostream>
|
||
|
||
XCEngine::XCEngine::Threading::Mutex mtx;
|
||
volatile bool updated = false;
|
||
|
||
void TryUpdate() {
|
||
if (mtx.try_lock()) {
|
||
updated = true;
|
||
mtx.unlock();
|
||
std::cout << "Update succeeded" << std::endl;
|
||
} else {
|
||
std::cout << "Update skipped (lock held)" << std::endl;
|
||
}
|
||
}
|
||
```
