向量push_back()给出编译器错误C2280

我试图将自定义类对象附加到相同类型的向量上,但是当我尝试编译我的代码时,编译器给出以下错误

gltf::gltf(const gltf &): attempting to reference a deleted function

我的函数将字符串(文件名)作为参数并加载该文件,然后解析该文件并填充其变量

功能如下:-

void enigma::loadModel(std::string file)
{       

    gltf stagingModel;
    stagingModel.loadAsset(file);   // populates my object with data
    model.push_back(stagingModel);  // appends the populated object to a vector array (this line generates the error)

    ....   // the rest of the code
}

我的gltf类简化如下:-

#pragma once
#include <iostream>
#include <vector>
#include <sstream>
#include <fstream>
#include "meshClass.h"
#include "bufferClass.h"
#include <gtx/quaternion.hpp>
#include <gtx/transform.hpp>

#include"stagingNodeClass.h"
#include"stagingMeshClass.h"
#include"stagingAccessorClass.h"
#include"stagingBufferViewClass.h"
#include"stagingImageClass.h"
#include"stagingSamplerClass.h"
#include"stagingTextureClass.h"
#include"stagingMaterialClass.h"
#include"stagingSkinClass.h"

class gltf
{
public:
    gltf();
    ~gltf();

    std::vector<meshClass> mesh;
    std::vector<char> bin;
    glm::mat4 camera;
    glm::mat4 scale;
    void loadAsset(std::string);

private:
    std::vector<stagingNodeClass> stagingNode;
    std::vector<stagingMeshClass> stagingMesh;
    std::vector<stagingAccessorClass> stagingAccessor;
    std::vector<stagingBufferViewClass>  stagingBufferView;
    std::vector<stagingImageClass> stagingImage;
    stagingSamplerClass stagingSampler;
    std::vector<stagingTextureClass> stagingTexture;
    std::vector<stagingMaterialClass> stagingMaterial;
    stagingSkinClass stagingSkins;
    bufferClass stagingBuffer;
    bool isCamera = false;

    bool node(std::string, std::string);
    int getValue(std::string);
    int getCamIndex(std::string);
    glm::mat4 getMatrix(std::string);
    glm::vec3 getVec3();
    glm::vec4 getVec4();
    float getFloatValue(std::string);
    void initScale();

    std::vector<int> getIntArray();
    std::vector<float> getFloatArray();

    std::string getName(std::string);

    std::fstream  asset;
    std::string line;

};

您得到的错误是gltf是不可复制对象的结果,因为它的副本构造函数被隐式删除。在向量上调用push_back要求被推送的对象是可复制的或可移动的,在后一种情况下,您需要明确传递一个不做的r值。

您尚未在gltf中明确删除副本构造函数,因此我想假设是gltf中存储的一个或多个对象,或者可能是gltf中存储的对象之一import { Action, Reducer } from 'redux'; // ----------------- // STATE - This defines the type of data maintained in the Redux store. export interface LoggedInUserState { userName: string, isAdmin: boolean, isUserManager: boolean } 中的(许多)向量本身是不可复制的,这导致您的类隐式删除其自己的副本构造函数。进行代码审核以找出哪个对象不可复制,然后删除该对象或为此类编写自己的副本构造函数(可能还会移动构造函数),或对该对象进行改造以使其可正确复制。
