JDK 7で追加されるクラス・メソッドを一覧してみようと思いました。標準APIのソースコードはJDKと一緒にインストールされるので（src.zip）、これを展開し、Javadocコメントの@sinceタグに1.7とあるものを抽出すればいいというのが最初の発想です。
JDK 7のソースコードからJavadocコメントの@sinceタグ部分抜粋
新しく導入されたクラスは、クラスのJavadocに記載される@sinceタグに1.7と書かれています。以下は、JDK 7で新規追加されるクラス javax.swing.JLayer の例です。
package javax.swing; :（中略） /** * {@code JLayer} is a universal decorator for Swing components :（中略） * @since 1.7 :（中略） */ public final class JLayer<V extends Component> extends JComponent implements Scrollable, PropertyChangeListener, Accessible {
以下は、java.util.logging.Loggerクラスに、JDK 7で新規追加されるメソッド getGlobal の例です。
/** * Return global logger object with the name Logger.GLOBAL_LOGGER_NAME. * * @return global logger object * @since 1.7 */ public static final Logger getGlobal() { return global; }
@since 1.7が記載されたクラスやメソッドを抽出するには
find, grep, awkでは、ちょっとつらい（同一行にクラス・メソッド情報がないため）ので、いろいろ考えてみましたが、これは自分でJavadocのDoclet実装を書き、@sinceタグで1.7の記述があるクラス・メソッドの名前だけ出力すればよいと思いました。
JavadocのDocletを書いてみる
そこで、見よう見まねで作ってみたのが以下です。
package jp.gr.java_conf.torutk.doclets; import com.sun.javadoc.ClassDoc; import com.sun.javadoc.MethodDoc; import com.sun.javadoc.RootDoc; import com.sun.javadoc.Tag; public class ListBySinceDoclet { private static final String TAG_SINCE = "@since"; public static boolean start(RootDoc root) { ClassDoc[] classDocs = root.classes(); for (ClassDoc classDoc : classDocs) { Tag[] sinceTags = classDoc.tags(TAG_SINCE); if (isSinceTagMatches(sinceTags)) { System.out.println(classDoc.qualifiedName() + " [class]"); } MethodDoc[] methodDocs = classDoc.methods(); for (MethodDoc methodDoc : methodDocs) { if (isSinceTagMatches(methodDoc.tags(TAG_SINCE))) { System.out.println(classDoc.qualifiedName() + "#" + methodDoc.name()); } } } return true; } private static boolean isSinceTagMatches(Tag[] tags) { for (Tag tag : tags) { if ("1.7".equals(tag.text())) { return true; } } return false; } }
自前のJavadocクラスを作るときは、特に継承するものはなく、public staticなstartメソッドを定義すればよいようです。引数に渡されるRootDocオブジェクトから芋づる的にたぐって、クラスやメソッドのJavadocコメントに書かれた@sinceタグを取り出し、値が1.7と一致するか調べ、一致していたらクラス名またはメソッド名をprintしているだけのコードです。
実行
カレントディレクトリをjdk 7のsrc.zip展開場所に移動し、自前のJavadocクラスを置いた場所と自前のJavadocクラス、解析対象パッケージを指定します。
