Method Detail

encode

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

Encode binary input stream into Base64 character stream

Parameters:

in - the InputStream to encode.

out - the OutputStream to which the encoded data is written.

Throws:

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

encode

public void encode(java.io.InputStream in,
          java.io.OutputStream out,
          boolean newLines)
            throws java.io.IOException

Encode binary input stream into Base64 character stream

Parameters:

in - the InputStream to encode.

out - the OutputStream to which the encoded data is written.

newLines - if true (default) the encoded data is written in max 76 character lines.

Throws:

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

decode

public void decode(java.io.InputStream in,
          java.io.OutputStream out)
            throws java.io.IOException

Decode Base64 input character stream into binary output stream.

Parameters:

in - the InputStream to decode.

out - the OutputStream to write the decoded data to.

Throws:

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

decode

public java.lang.String decode(java.io.InputStream in)
                        throws java.io.IOException

Decode Base64 input character stream into a String representation of decoded binary stream.

Throws:

java.io.IOException

encodedSize

public static int encodedSize(int length,
              boolean newLines)

Compute the size of BASE64-encoded stream.

Parameters:

length - the number of bytes to encode

newLines - true if new-line characters will be added to encoded stream, false otherwise

Returns:

the number of BASE64 bytes that will be produced while calling Base64.encode() on the specified number of bytes

See Also:

encode(java.io.InputStream, java.io.OutputStream)

decodedSize

public static int decodedSize(byte[] data,
              boolean newLines)

Compute the size of BASE64-decoded stream.

Parameters:

data - BASE64 encoded data produced by Base64.encode()

newLines - true if new-line characters have been added to the encoded stream, false otherwise

Returns:

the number of bytes that will be produced when decoding the specified BASE64 stream

See Also:

decode(java.io.InputStream, java.io.OutputStream)

main

public static void main(java.lang.String[] a)
                 throws java.lang.Exception

Encodes a binary file into a BASE64 text file or vice versa

Throws:

java.lang.Exception
