类 IOKits

java.lang.Object

cn.webfuse.core.kit.io.IOKits

public class IOKits
extends Object

copy from vjtools

IO Stream/Reader相关工具集. 固定encoding为UTF8.

建议使用Apache Commons IO和Guava关于IO的工具类(com.google.common.io.*), 在未引入Commons IO时可以用本类做最基本的事情.

1. 安静关闭Closeable对象

2. 读出InputStream/Reader全部内容到String 或 List

3. 读出InputStream/Reader一行内容到String

4. 将String写到OutputStream/Writer

5. 将String 转换为InputStream/Reader

5. InputStream/Reader与OutputStream/Writer之间复制的copy
