Base64OutputStream
public Base64OutputStream(OutputStream out)
Creates aBase64OutputStream
that writes the encoded data to the given output stream using the default line length (76) and line separator (CRLF).- Parameters:
out
- underlying output stream.
-
Base64OutputStream
public Base64OutputStream(OutputStream out, int lineLength)
Creates aBase64OutputStream
that writes the encoded data to the given output stream using the given line length and the default line separator (CRLF).The given line length will be rounded up to the nearest multiple of 4. If the line length is zero then the output will not be split into lines.
- Parameters:
out
- underlying output stream.lineLength
- desired line length.
-
Base64OutputStream
public Base64OutputStream(OutputStream out, int lineLength, byte[] lineSeparator)
Creates aBase64OutputStream
that writes the encoded data to the given output stream using the given line length and line separator.The given line length will be rounded up to the nearest multiple of 4. If the line length is zero then the output will not be split into lines and the line separator is ignored.
The line separator must not include characters from the BASE64 alphabet (including the padding character
=
).- Parameters:
out
- underlying output stream.lineLength
- desired line length.lineSeparator
- line separator to use.
