public static class Base64.InputStream
extends java.io.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 |

public InputStream(java.io.InputStream in)
Base64.InputStream in DECODE mode.in - the java.io.InputStream from which to read data.public InputStream(java.io.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)
Note: Technically, this makes your encoding non-compliant.
