[英]C++ function with a struct vector as a return value
I want to create a private function in C++ (VS2010). 我想在C ++(VS2010)中创建一个私有函数。 It should return a vector/array of structs/userdefined type. 它应该返回一个向量/结构/用户定义类型的数组。
However I think my declaration of the function in the cpp file is perhaps wrong. 但是我认为我在cpp文件中声明该功能可能是错误的。 Or maybe already in the header. 也许已经在标题中了。 Can somebody have a look at it? 有人可以看看吗?
My header looks like this: 我的标题看起来像这样:
#pragma once
using namespace std;
#include <algorithm>
#include <vector>
class clsWString2
{
private:
struct udtWChar2
{
wstring Text;
int OrigPos;
};
bool m_bDirty;
vector<udtWChar2>pToWChar2(wstring u);
vector<udtWChar2>m;
public:
clsWString2(void);
~clsWString2(void);
void ReplaceCompareBinary(wstring uSearchFor, wstring uReplaceBy);
void ReplaceCompareText(wstring uSearchFor,wstring uReplaceBy);
void ReplaceByPos(int uStartPos1Based,int uLen0Based, wstring uReplaceBy);
void FeedString(wstring u);
void Append(wstring u);
wstring CharAtPos(int uIndex);
int OrigPos(int uIndex);
};
And my .cpp file looks like this: 我的.cpp文件看起来像这样:
#include "StdAfx.h"
#include "clsWString2.h"
clsWString2::clsWString2(void)
{
m.resize(0);
}
clsWString2::~clsWString2(void)
{
}
vector<udtWChar2> clsWString2::pToWChar2(wstring u)
{
vector<udtWChar2> n;
n.resize(0);
for (int i=0;i<u.size();i++)
{
wstring sChar;
sChar=u.substr(i,1);
udtWChar2 nc;
nc.Text =sChar;
nc.OrigPos=i;
n.push_back (nc);
}
return n;
}
In the source file, when you define the function, the return type is not in the scope of the class so the class in the vector needs to be fully qualified: 在源文件中,当您定义函数时,返回类型不在类的范围内,因此向量中的类需要完全限定:
vector<clsWString2::udtWChar2> clsWString2::pToWChar2(wstring u)
{
...
}
啊,我明白了:
vector<clsWString2::udtWChar2> clsWString2::pToWChar2(wstring u)
You can not use directly udtWChar2 as type , you need define type def or you need use as struct udtWChar2 您不能直接将udtWChar2用作类型,需要定义类型def或将其用作结构udtWChar2
Like : 喜欢 :
in .h 在.h中
vector < struct udtWChar2 > pToWChar2(wstring u);
vector < struct udtWChar2 > m;
in .cpp 在.cpp中
vector < struct clsWString2::udtWChar2 > clsWString2::pToWChar2(wstring u)
