|
||
|
|
|
||
|
|
```cpp
|
||
|
|
String Trim() const;
|
||
|
|
```
|
||
|
|
|
||
|
|
移除字符串两端的空白字符（空格、制表符、换行符、回车符），返回一个新的 String 对象，原字符串不变。
|
||
|
|
|
||
|
|
**参数：** 无
|
||
|
|
|
||
|
|
**返回：** 去除两端空白后的新 String 对象
|
||
|
|
|
||
|
|
**复杂度：** O(n)，其中 n 为字符串长度
|
||
|
|
|
||
|
|
**示例：**
|
||
|
|
```cpp
|
||
|
|
#include "XCEngine/Containers/String.h"
|
||
|
|
#include <iostream>
|
||
|
|
|
||
|
|
int main() {
|
||
|
|
XCEngine::Containers::String s(" Hello World ");
|
||
|
|
|
||
|
|
XCEngine::Containers::String trimmed = s.Trim();
|
||
|
|
std::cout << "\"" << trimmed.CStr() << "\"" << std::endl; // 输出: "Hello World"
|
||
|
|
|
||
|
|
XCEngine::Containers::String s2("\t\n test \t\n");
|
||
|
|
std::cout << "\"" << s2.Trim().CStr() << "\"" << std::endl; // 输出: "test" (空格、制表符、换行、回车被移除)
|
||
|
|
|
||
|
|
return 0;
|
||
|
|
}
|
||
|
|
```
