Examples of TsvParser

com.asakusafw.runtime.io.TsvParser

TSVファイルを解析してレコードを読み出す。

次のように利用する。

 Reader reader = ...; SomeModel model = new SomeModel(); try { TsvParser parser = new TsvParser(reader); while (parser.hasNext()) { parser.fill(model.getHogeOption()); parser.fill(model.getFooOption()); parser.fill(model.getBarOption()); performModelAction(model); } } finally { reader.close(); }

特に指定がない限り、このクラスのメソッドの引数に {@code null}を指定した場合には {@link NullPointerException}がスローされる。
