VPasCode 完整指南：現代開發的即時圖形即程式碼

// 1. 核心介面
interface Identifiable {
    id: string;
}

// 2. 結構化資料型別的列舉
enum ProjectStatus {
    PLANNING = "PLANNING",
    ACTIVE = "ACTIVE",
    COMPLETED = "COMPLETED"
}

// 3. 葉類別（關聯物件）
class Project {
    public projectId: string;
    public name: string;
    private status: ProjectStatus;

    constructor(id: string, name: string) {
        this.projectId = id;
        this.name = name;
        this.status = ProjectStatus.PLANNING;
    }

    public updateStatus(newStatus: ProjectStatus): void {
        this.status = newStatus;
    }
}

// 4. 抽象基類別
abstract class Employee implements Identifiable {
    public id: string;
    protected name: string;
    protected email: string;
    private salary: number;

    constructor(id: string, name: string, email: string, salary: number) {
        this.id = id;
        this.name = name;
        this.email = email;
        this.salary = salary;
    }

    public abstract calculateBonus(): number;
    
    public getContactInfo(): string {
        return `${this.name} <${this.email}>`;
    }
}

// 5. 具體類別：經理（彙整專案）
class Manager extends Employee {
    public departmentName: string;
    private assignedProjects: Project[]; // 聚合關聯

    constructor(id: string, name: string, email: string, salary: number, dept: string) {
        super(id, name, email, salary);
        this.departmentName = dept;
        this.assignedProjects = [];
    }

    public calculateBonus(): number {
        return 5000 + (this.assignedProjects.length * 1000);
    }

    public assignProject(project: Project): void {
        this.assignedProjects.push(project);
    }
}

// 6. 具體類別：工程師（直接實作抽象方法）
class Engineer extends Employee {
    public primarySkill: string;

    constructor(id: string, name: string, email: string, salary: number, skill: string) {
        super(id, name, email, salary);
        this.primarySkill = skill;
    }

    public calculateBonus(): number {
        return 2500;
    }
}

// 7. 根組合類別（擁有部門與員工的生命週期）
class Department {
    public code: string;
    private manager: Manager;          //關聯關聯
    private staff: Engineer[];         //組合關聯

    constructor(code: string, manager: Manager) {
        this.code = code;
        this.manager = manager;
        this.staff = [];
    }

    public onboardEngineer(engineer: Engineer): void {
        this.staff.push(engineer);
    }

    public getHeadcount(): number {
        return this.staff.length + 1; // 工程師 + 經理
    }
}
