[Eclipse plug-in development] Javadoc acquisition

I don't think anyone is interested, but I had a little trouble finding it, so I'll write it down as a reminder.

ʻOrg.eclipse.jdt.ui.JavadocContentAcces # getContentReader` is used.

import org.eclipse.jdt.core.IMember;
import org.eclipse.jdt.ui.JavadocContentAccess;
//・ ・ ・

	public static String getJavadoc(IMember member) {
		try {
			Reader reader = JavadocContentAccess.getContentReader(member, false);
			if (reader == null) {
				return null;
			}
			try {
				StringBuilder buf = new StringBuilder();
				int ch;
				while ((ch = reader.read()) != -1) {
					buf.append((char) ch);
				}
				return buf.toString();
			} finally {
				reader.close();
			}
		} catch (IOException | JavaModelException e) {
			return null;
		}
	}

• MEMO

ʻOrg.eclipse.jdt.ui.JavadocContentAccess is ** ʻorg.eclipse.jdt.ui**, ʻOrg.eclipse.jdt.core.IMember is ** ʻorg.eclipse.jdt.core ** Can be used by putting in a dependency.

ʻI Member` is the parent interface for Field, Method, Class, Constructor (IInitializer), etc.

To find out how to access to ʻI Member, go to ʻI Java Project and ʻI Type`.
