文字解析元件

常見拆解文字有兩種方式，為了避免修改格式造成程式修改容易建立共用元件

• byte長度切割

• char長度切割

class TextCutRuleslSeriveTest {
	private final String UTF8 = "utf-8";
	ITextCutRuleslSerive<List<String>> textCutRuleslSerive = new TextCutRuleslSerive<>();

	public TextCutRuleslSeriveTest() {
		textCutRuleslSerive.addRule(i -> i.startsWith("ST01"), getST01());
		textCutRuleslSerive.addRule(i -> i.startsWith("ST02"), getST02());
		textCutRuleslSerive.addRule(i -> i.startsWith("ST03"), getST03());

	}

	@Test
	public void test_give_4Line_reutrn_4Line() {

		// WHEN 轉換
		List<List<String>> list = textCutRuleslSerive.to(line);
