Base64Decoder
public Base64Decoder(java.lang.String input)
- Create a decoder to decode a String.
- Parameters:
input
- The string to be decoded.
Base64Decoder
public Base64Decoder(java.io.InputStream in,
java.io.OutputStream out)
- Create a decoder to decode a stream.
- Parameters:
in
- The input stream (to be decoded).out
- The output stream, to write decoded data to.
process
public void process()
throws java.io.IOException,
Base64FormatException
- Do the actual decoding.
Process the input stream by decoding it and emiting the resulting bytes
into the output stream.
- Throws:
- java.io.IOException - If the input or output stream accesses failed.
- Base64FormatException - If the input stream is not compliant
with the BASE64 specification.
processString
public java.lang.String processString()
throws Base64FormatException
- Do the decoding, and return a String.
This methods should be called when the decoder is used in
String mode. It decodes the input string to an output string
that is returned.
- Throws:
- java.lang.RuntimeException - If the object wasn't constructed to
decode a String.
- Base64FormatException - If the input string is not compliant
with the BASE64 specification.
main
public static void main(java.lang.String[] args)
- Test the decoder.
Run it with one argument: the string to be decoded, it will print out
the decoded value.
