Fixed the following issues in XCEngine Core module documentation: - Added 'using namespace XCEngine::Core;' to all code examples that use Core types (Event, FileWriter, etc.) without full namespace qualification - Added missing '#include <XCEngine/Containers/String.h>' to FileWriter examples that use Containers::String - Added '#include <string>' to Flush.md example using std::to_string Affected files: - core/core.md: Added using directive and Containers include - event/*.md: Added using namespace to all 8 event doc files - filewriter/*.md: Added using namespace and proper includes to all 6 files

Event::Invoke
void Invoke(Args... args);
调用所有订阅的回调。
描述
依次调用所有已订阅的回调函数。在调用前会自动处理待退订的回调。回调是在锁外执行的,因此可以在回调中安全地进行订阅/退订操作。线程安全。
参数:
args- 传递给回调的参数
复杂度: O(n) 其中 n 为订阅数量
示例:
#include <XCEngine/Core/Event.h>
using namespace XCEngine::Core;
// 无参数事件
Event<> frameEndEvent;
frameEndEvent.Subscribe([]() {
printf("Frame ended\n");
});
// 带参数事件
Event<int, const char*> playerDiedEvent;
playerDiedEvent.Subscribe([](int playerId, const char* reason) {
printf("Player %d died: %s\n", playerId, reason);
});
// 触发事件
frameEndEvent.Invoke();
playerDiedEvent.Invoke(1, "fell off a cliff");
