FileWriter
命名空间: XCEngine::Core
类型: class
头文件: XCEngine/Core/FileWriter.h
描述: 文件写入工具类,提供简单的文件写入操作封装。
概述
FileWriter 是一个轻量级的文件写入工具,封装了 FILE* 接口,提供便捷的字符串和二进制数据写入功能。它支持追加模式和自动资源管理(RAII)。
公共方法
| 方法 | 描述 |
|---|---|
FileWriter() |
默认构造(不打开文件) |
FileWriter(filePath, append) |
构造并打开文件 |
~FileWriter() |
析构函数,自动关闭文件 |
Open |
打开文件,append=true 时为追加模式 |
Close |
关闭文件 |
IsOpen |
检查文件是否已打开 |
Write |
写入数据 |
Flush |
刷新缓冲区 |
使用示例
#include <XCEngine/Core/FileWriter.h>
#include <XCEngine/Containers/String.h>
using namespace XCEngine::Core;
// 方式1:构造时打开
FileWriter writer("output.txt", false);
if (writer.IsOpen()) {
writer.Write("Hello, World!\n");
writer.Write("Line 2\n");
writer.Flush();
}
// 方式2:先构造再打开
FileWriter writer2;
if (writer2.Open("log.txt")) {
writer2.Write("Application started\n");
writer2.Close();
}
// 追加模式
FileWriter appendWriter("log.txt", true);
if (appendWriter.IsOpen()) {
appendWriter.Write("Another log entry\n");
appendWriter.Flush();
}
// 使用 String 写入
Containers::String content = "Content written from String";
FileWriter writer3("data.txt");
writer3.Write(content);
