- org.jvnet.staxex.Base64EncoderStream
-
- All Implemented Interfaces:
java.io.Closeable,java.io.Flushable,java.lang.AutoCloseable
public class Base64EncoderStream extends java.io.FilterOutputStreamThis 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.

-
write
public void write(byte[] b) throws java.io.IOExceptionEncodesb.lengthbytes to this output stream.- Overrides:
writein classjava.io.FilterOutputStream- Parameters:
b- the data to be written.- Throws:

-
write
public void write(int c) throws java.io.IOExceptionEncodes the specifiedbyteto this output stream.- Overrides:
writein classjava.io.FilterOutputStream- Parameters:
c- thebyte.- Throws:
java.io.IOException- if an I/O error occurs.
-
flush
public void flush() throws java.io.IOExceptionFlushes this output stream and forces any buffered output bytes to be encoded out to the stream.- Specified by:
