All Implemented Interfaces:
Closeable, Flushable, AutoCloseable
public class Base64OutputStream extends OutputStream
This class implements section 6.8. Base64 Content-Transfer-Encoding from RFC 2045 Multipurpose Internet Mail Extensions (MIME) Part One: Format of Internet Message Bodies by Freed and Borenstein.

Code is based on Base64 and Base64OutputStream code from Commons-Codec 1.4.

    • Base64OutputStream

      public Base64OutputStream(OutputStream out)
      Creates a Base64OutputStream 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 a Base64OutputStream 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 a Base64OutputStream 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.
