vector使用

1.遍历

vector<int>::iterator it = v.begin();
for(; it != v.end(); ++it)
{
	cout<<(*it)<<" ";
}
           

2.find查找并删除, 通过重载==, 传入对象

InfomFind = Info("xx", "yy");
vector<Info>::iterator itTmp = find(dataVector.begin(), dataVector.end(), mFind);
if (itTmp != dataVector.end())
{
	itTmp = dataVector.erase(itTmp); 
}

class Info
{
public:
	Info()
	{
		cameraIndexCode = wxEmptyString;
		planId = wxEmptyString;
		presetName = wxEmptyString;
		presetIndex = -1;
		playIndex = -1;
	}

	Info(wxString id, wxString code)
	{
		cameraIndexCode = code;
		planId = id;
		presetName = wxEmptyString;
		presetIndex = -1;
		playIndex = -1;
	}

	bool operator()(const Info& left, const Info& right)
	{
		return left.playIndex < right.playIndex;
	}

	bool operator==(InfoTmp)
	{
		if (cameraIndexCode.IsSameAs(Tmp.cameraIndexCode) || planId.IsSameAs(Tmp.planId))
		{
			return true;
		}
		return false;
	}

	wxString cameraIndexCode;
	wxString planId;
	wxString presetName;
	int presetIndex;
	int playIndex;
};
           

3.删除

for (vector<Info>::iterator it = dataVector.begin(); it != dataVector.end();)
	{
		if (it->xx== xx)
		{
			it = dataVector.erase(it);
		}
		else
		{
			++it;
		}
	}
           

4. 排序 通过重载(), 传入方法

std::sort(devs.begin(), devs.end(), Info());
           

5.find_if查找 通过重载(), 传入对象

class Info
{
public:
	Info()
	{
		Name = wxEmptyString;
		DeviceCount = 0;
		devs.clear();
	}
	bool operator()(const Info & scheme)
	{
		return Name == scheme.Name;
	}

	wxString Name;
	int DeviceCount;
};

List.erase(std::find_if(List.begin(), List.end(), scheme));
