Constructor Detail

StiBase64EncoderUtil

public StiBase64EncoderUtil(java.io.OutputStream stream)

Construct a Base64Encoder waiting on calls to its translate() method. Base64Encoder must be flushed to write internally buffered data to output stream.

Parameters:

stream - stream to write encoded bytes to

Method Detail

encode

public static void encode(java.io.InputStream input,
                          java.io.OutputStream out)
                   throws java.io.IOException

Encode bytes from input stream and write encoded bytes to output stream.

Parameters:

input - input stream

out - output stream

Throws:

java.io.IOException - if an I/O error occurs

encode

public static byte[] encode(byte[] data)

Encode given byte array into an encoded byte array.

Parameters:

data - the byte array to be encoded

Returns:

Base64 encoded characters as byte array

encode

public static java.lang.String encode(java.lang.String data)

encode

public static byte[] encode(byte[] data,
                            int begin,
                            int end)

Encode given byte array into an encoded byte array.

Parameters:

data - the byte array to be encoded

begin - index of the first byte to start from

end - index after the last byte

Returns:

Base64 encoded characters as byte array

flush

public void flush()
           throws java.io.IOException

Writes all encoded characters.

Throws:

java.io.IOException - if an I/O error occurs. In particular, an IOException may be thrown if the output stream has been closed.
