Base64DecodeStream (org.apache.xmlgraphics:xmlgraphics-commons 2.7 API)

java.lang.Object
- java.io.InputStream
- - org.apache.xmlgraphics.util.io.Base64DecodeStream

All Implemented Interfaces:

Closeable, AutoCloseable
```
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)."
 
```
