Base64OutputStream生成没有换行的构造方法

Base64OutputStream类的源码
public class Base64OutputStream extends BaseNCodecOutputStream {
    public Base64OutputStream(OutputStream out) {
        this(out, true);
    }


    public Base64OutputStream(OutputStream out, boolean doEncode) {
        super(out, new Base64(false), doEncode);
    }
    /**
     * Creates a Base64OutputStream such that all data written is either Base64-encoded or Base64-decoded to the
     * original provided OutputStream.
     * 
     * @param out
     *            OutputStream to wrap.
     * @param doEncode
     *            true if we should encode all data written to us, false if we should decode.
     * @param lineLength
     *            If doEncode is true, each line of encoded data will contain lineLength characters (rounded down to
     *            nearest multiple of 4). If lineLength <=0, the encoded data is not divided into lines. If doEncode is
     *            false, lineLength is ignored.
     * @param lineSeparator
     *            If doEncode is true, each line of encoded data will be terminated with this byte sequence (e.g. \r\n).
     *            If lineLength <= 0, the lineSeparator is not used. If doEncode is false lineSeparator is ignored.
     */
    public Base64OutputStream(OutputStream out, boolean doEncode, int lineLength, byte[] lineSeparator) {
        super(out, new Base64(lineLength, lineSeparator), doEncode);
    }
}


看到同事生成带有换行符base64,他用Notepad++一个一个删掉，感觉一定会有重载的函数来实现不用换行；看了一下Base64OutputStream的源码果然有一个构造方法，如下：
 OutputStream os64 = new Base64OutputStream(out,true,0,null);
