在许多编程语言中，可以使用自定义比较函数来按照对象的特定成员值对对象的向量进行排序。以下是一些常见编程语言的示例代码：

Python示例代码：

class Person:
    def __init__(self, name, age):
        self.name = name
        self.age = age

people = [
    Person("John", 30),
    Person("Alice", 25),
    Person("Bob", 35)
]

sorted_people = sorted(people, key=lambda x: x.age)
for person in sorted_people:
    print(person.name, person.age)

Java示例代码：

import java.util.ArrayList;
import java.util.Collections;
import java.util.Comparator;
import java.util.List;

class Person {
    String name;
    int age;

    public Person(String name, int age) {
        this.name = name;
        this.age = age;
    }
}

public class Main {
    public static void main(String[] args) {
        List people = new ArrayList<>();
        people.add(new Person("John", 30));
        people.add(new Person("Alice", 25));
        people.add(new Person("Bob", 35));

        Collections.sort(people, Comparator.comparingInt(person -> person.age));
        for (Person person : people) {
            System.out.println(person.name + " " + person.age);
        }
    }
}

C++示例代码：

#include 
#include 
#include 

struct Person {
    std::string name;
    int age;

    Person(const std::string& name, int age) : name(name), age(age) {}
};

bool compareByAge(const Person& a, const Person& b) {
    return a.age < b.age;
}

int main() {
    std::vector people = {
        Person("John", 30),
        Person("Alice", 25),
        Person("Bob", 35)
    };

    std::sort(people.begin(), people.end(), compareByAge);
    for (const Person& person : people) {
        std::cout << person.name << " " << person.age << std::endl;
    }

    return 0;
}

这些示例代码都是按照Person对象的age成员值对对象向量进行排序的示例。可以根据需要修改比较函数或成员变量以适应不同的排序需求。
