org.apache.batik.util.Base64DecodeStream
- All Implemented Interfaces:
Closeable
,AutoCloseable
This class implements a Base64 Character decoder as specified in RFC1113.
Unlike some other encoding schemes there is nothing in this encoding that
tells the decoder where a buffer starts or stops, so to use it you will need
to isolate your encoded data into a single chunk and then feed them
this decoder. The simplest way to do that is to read all of the encoded
data into a string and then use:
byte data[]; InputStream is = new ByteArrayInputStream(data); is = new Base64DecodeStream(is);On errors, this class throws a IOException with the following detail strings:
"Base64DecodeStream: Bad Padding byte (2)." "Base64DecodeStream: Bad Padding byte (1)."
