Adapterパターンの練習

using UnityEngine;
using System;

//使い方
public class TestScript : MonoBehaviour
{
	void Start ()
	{
		var a = new GoodHellow1 ("いーちゃん", 20, "。戯言だけどね！");
		a.VeryGoodHellow ();
		var b = new GoodHellow2 ("なると", 20, "ってばよ");
		b.VeryGoodHellow ();
	}
}

//すでに用意されてある機能/ライブラリとか
public class Hellow
{
	private string name;
	private int age;

	public Hellow (string name, int age)
	{
		this.name = name;
		this.age = age;
	}

	public string SayHellow ()
	{
		return "こんにちは!" + GetName () + "です :)";
	}

	public string GetName ()
	{
		return this.name;
	}

	public int GetAge ()
	{
		return age;
	}
}

//欲しい機能のinterface
//めっちゃかっこよく挨拶したいよ・・・
public interface HellowInterface
{
	void VeryGoodHellow ();
}

//Adapterパターン(継承)
public class GoodHellow1 : Hellow,HellowInterface
{
	private string keyword;

	public GoodHellow1 (string name, int age, string keyword) : base (name, age)
	{
		this.keyword = keyword;
	}

	public void VeryGoodHellow ()
	{
		Debug.Log ("やあ！諸君!僕の名前は" + GetName () + "です!年齢は" + GetAge () + GetKeyword ());
	}

	public string GetKeyword ()
	{
		return this.keyword;
	}
	
}

//Adapterパターン(移譲)
public class GoodHellow2 : HellowInterface
{
	private Hellow hellow;
	private string keyword;

	public GoodHellow2 (string name, int age, string keyword)
	{
		hellow = new Hellow (name, age);
	}

	public void VeryGoodHellow ()
	{
		Debug.Log ("やあ！諸君!僕の名前は" + hellow.GetName () + "です!年齢は" + hellow.GetAge () + GetKeyword ());
	}

	public string GetKeyword ()
	{
		return this.keyword;
	}
}
