public static class Base64.InputStream extends FilterInputStream
Base64.InputStream will read data from another java.io.InputStream, given in the
constructor, and encode/decode to/from Base64 notation on the fly.Base64| Modifier and Type | Field and Description |

Base64.InputStream in DECODE mode.in - the java.io.InputStream from which to read data.public Base64.InputStream(InputStream in, int options)
Base64.InputStream in either ENCODE or DECODE mode.
Valid options:
ENCODE or DECODE: Encode or Decode as data is read.
DONT_BREAK_LINES: don't break lines at 76 characters
(only meaningful when encoding)
<i>Note: Technically, this makes your encoding non-compliant.</i>
