C ++“地图不是类型”错误

Question

This is my header file:

/**
 * Job.h
 *
 **/

#ifndef JOB_
#define JOB_

#include <map>
#include <string>
#include <algorithm>
#include <cstdlib>
#include <iomanip>
#include <vector>

class Job {

private:

int resourceId;
int inputRepresentation;
int outputRepresentation;

//Effects associative array
//Maps an effect to a map of it's attributes
//effectsMap[effect][attribute]=value
map< std::string, map<std::string, int> > *effectsMap;

public:

//constructors
Job();
Job(int resId, int inputRep, int outputRep);

//destructor
virtual ~Job();


//getters
int getInputRepresentation() const;
int getOutputRepresentation() const;
int getResourceId() const;


//setters
void setInputRepresentation(int inputRepresentation);
void setOutputRepresentation(int outputRepresentation);
void setResourceId(int resourceId);
void setRepresentations(std::map *rep);

void addEffect(std::string effect, map<std::string, int> attributesMap);



};


#endif

Now Ii will get to the point:

void setRepresentations(std::map *rep)

Gives the following error: "map is not a type" This is weird because it looks like eclipse manages to properly link to the stl library... And I do have a private field of map that seems to be fine.

Any ideas?

Answer 1

您需要指定地图的完整类型，包括< >内的类型：

void setRepresentations(std::map<std::string, int> *rep);

Answer 2

您在地图前面缺少std:: 。

Answer 3

std:map is a template , not a type . A type would be std::map<std::string, int> .

What exactly is setRepresentations supposed to do? Why does the signature not fully specify what type of map it should be working with, just like addEffect does?

Answer 4

您需要为map指定名称空间，因此应为std::map 。
