Constructor Detail

Base64OutputStream

public Base64OutputStream(java.io.OutputStream outputStream)

It builds a base64 encoding output stream writing the encoded data in the given underlying stream.

The encoded data is wrapped to a new line (with a CRLF sequence) every 76 bytes sent to the underlying stream.

Parameters:

outputStream - The underlying stream.

Base64OutputStream

public Base64OutputStream(java.io.OutputStream outputStream,
                          int wrapAt)

It builds a base64 encoding output stream writing the encoded data in the given underlying stream.

The encoded data is wrapped to a new line (with a CRLF sequence) every wrapAt bytes sent to the underlying stream. If the wrapAt supplied value is less than 1 the encoded data will not be wrapped.

Parameters:

outputStream - The underlying stream.

wrapAt - The max line length for encoded data. If less than 1 no wrap is applied.
