Class Base64DecodeStream
java.lang.Object
java.io.InputStream
org.apache.xmlgraphics.util.io.Base64DecodeStream
- All Implemented Interfaces:
- Closeable
public class Base64DecodeStream
- extends InputStream
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)."
