どう書く？org
tailの実装
takeru #6818(2008-07-24 13:57) 評価-10/12=-0.83
‘tail’を実装してください。
巨大なファイルでも効率的に動作するようにしてください。
最低限必要な機能は、
行数指定
「-f」パラメータの対応
です。

tailの仕様がわかりません。
検索すると概要はわかるのですが、実際にどういった動作をさせれば良いのでしょう？
UNIX環境が無いのでどうしたらよいのか…。

たしかにお題を出す人にも、もうすこし丁寧に出題してほしい感じがしますね。
たぶんですが、
意訳すると以下のような感じになるのではないでしょうか？
1. 指定されたファイルの最後尾から N行表示すること
2. ファイルの更新を監視して、指定のファイルが更新された場合に、
更新分のうち、最後尾からN行を表示すること
「2.」更新分なので前回表示続きからという点が注意事項だと思います。
# 「-f」 を実装しなさいというあたり、
以前あったファイルの更新を監視するお題の
派生と考えられるのかな？

対象がファイルの場合には、予めファイル末尾を基準にシークします。これによってファイルサイズに依存しない処理時間を実現しています。
起動方法は
java Tail [-f] [-] []
-f: ファイル末尾まで読み込んでも終了せず、ファイルが成長した部分をポーリングで表示する（ファイル名を与えない場合は無視する）。
num: ファイル末尾からnum行を表示する（デフォルトは10行）。
ファイル名: 表示するファイル名。省略した場合は標準入力。
です。 1

バッチです。カバレッジ稼ぎのようでちょっと恥ずかしいのですが、あまり処理を複雑に
したくなかったので、標準入力からの入力や-fオプションは実装しませんでした。
e.g.
C:\>tail 3 tail.bat
set /a i-=%1
endlocal & more +%i% %p%
goto :EOF
以下の参考サイトのものはもっと複雑で頭が下がります。

SQLite系のポーリングについて
SQLite DBをポーリングする場合 orgDB->copy->tempDBにコピーしなければなないので
1.orgDB timestampをみる。監視時間と比較 更新されてないなら 打ち切り
2.更新されているなら、コピー ->tempDB ポーリング
がいい。
