方法详细资料

open

public JSONBean.Writer open(PrintWriter writer)
                     throws IOException

Notice that, closing the return JSONBean.Writer will not close the writer passed in, you still need to close the writer by yourself.

This is because that, we can only finish the json after you call Closeable.close(). So if we just close the writer, you can write nothing after finished the json.

抛出:

IOException

dumpAllBeans

public static void dumpAllBeans()
                         throws IOException,
                                MalformedObjectNameException
