org.jvnet.staxex.Base64EncoderStream
- All Implemented Interfaces:
Closeable
,Flushable
,AutoCloseable
This class implements a BASE64 Encoder. It is implemented as
a FilterOutputStream, so one can just wrap this class around
any output stream and write bytes into this filter. The Encoding
is done as the bytes are written out.
