オブジェクトデータベース登録用にコンポジットパターンを実装してみた。
クラス宣言部分のみを抽出すると、とりあえず以下の４つがメインの実装。
public interface KsIbasic
public abstract class KsAbBasic implements com.keystonebrand.squid.lib.KsIbasic
public abstract class KsAbComposite<T> extends KsAbBasic
public class KsName extends KsAbComposite<String>
使用例:
KsName wEgi = new KsName("超シャープな動きを実現するエギ");
KsName wEgiSharp = new KsName("エギシャープ");
KsName wMonroEgi = new KsName("モンローエギ");
KsName wMetalicall = new KsName("メタリカルカラー");
wEgi.add_child(wEgiSharp);
wEgi.add_child(wMonroEgi);
wEgiSharp.add_child(wMetalicall);
