Constructor Detail

Base64OutputStream

public Base64OutputStream(Writer out)

Creates a new Base64OutputStream that will write the encoded data to the passed Writer.

Parameters:

out - the Writer to which the encoded data will be written.

Method Detail

write

public void write(int b)
           throws IOException

Writes a byte. This method will block until the byte is actually written.

Parameters:

b - the byte

Throws:

IOException - If an I/O error has occurred.

write

public void write(byte[] b,
                  int off,
                  int len)
           throws IOException

Writes a subarray of bytes.

Parameters:

b - the data to be written

off - the start offset in the data

len - the number of bytes to be written

Throws:

IOException - If an I/O error has occurred.

write

public void write(InputStream is)
           throws IOException

Writes a inputStream.

Parameters:

is - the inputStream to be written

Throws:

IOException - If an I/O error has occurred.

flush

public void flush()
           throws IOException

Throws:

IOException

close

public void close()
           throws IOException

Closes the stream.

Throws:

IOException - If an I/O error has occurred.

empty_buffer

protected void empty_buffer()
                     throws IOException

Encode all buffered bytes and write the encoded bytes to the output stream.

Throws:

IOException - If an I/O error has occurred.

encode

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

Encode an array of bytes into an array of chars using base64 encoding.

Parameters:

data - The bytes to be encoded.

Returns:

An array of chars that contain the base64-encoded data.

encode

public static char[] encode(byte[] data,
                            boolean wrap)

Encode an array of bytes into an array of chars using base64 encoding.

Parameters:

data - The bytes to be encoded.

wrap - true if should wrap lines

Returns:

An array of chars that contain the base64-encoded data.

encode

public static char[] encode(byte[] data,
                            int off,
                            int len)

Encode an array of bytes into an array of chars using base64 encoding.

Parameters:

data - The bytes to be encoded.

off - The starting offset in data

len - The number of bytes to encode.

Returns:

An array of chars that contain the base64-encoded data.

encode

public static char[] encode(byte[] data,
                            int off,
                            int len,
                            boolean wrap)

Encode an array of bytes into an array of chars using base64 encoding.

Parameters:

data - The bytes to be encoded.

off - The starting offset in data

len - The number of bytes to encode.

wrap - true if should wrap lines

Returns:

An array of chars that contain the base64-encoded data.
