public class Base64InputStream extends BaseNCodecInputStream
The default behaviour of the Base64InputStream is to DECODE, whereas the default behaviour of the Base64OutputStream is to ENCODE, but this behaviour can be overridden by using a different constructor.
This class implements section 6.8. Base64 Content-Transfer-Encoding from RFC 2045 Multipurpose Internet Mail Extensions (MIME) Part One: Format of Internet Message Bodies by Freed and Borenstein.
Since this class operates directly on byte streams, and not character streams, it is hard-coded to only encode/decode character encodings which are compatible with the lower 127 ASCII chart (ISO-8859-1, Windows-1252, UTF-8, etc).

|---|
Base64InputStream(InputStream in)
Creates a Base64InputStream such that all data read is Base64-decoded from the original provided InputStream.
|
Base64InputStream(InputStream in,
boolean doEncode)
Creates a Base64InputStream such that all data read is either Base64-encoded or Base64-decoded from the original
provided InputStream.
|
Base64InputStream(InputStream in,
boolean doEncode,
int lineLength,
byte[] lineSeparator)
Creates a Base64InputStream such that all data read is either Base64-encoded or Base64-decoded from the original
provided InputStream.

in - InputStream to wrap.doEncode - true if we should encode all data read from us, false if we should decode.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.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.Copyright © 2002–2014 The Apache Software Foundation. All rights reserved.
