Class Base32OutputStream

  • All Implemented Interfaces:
    Closeable, Flushable, AutoCloseable

    public class Base32OutputStream
    extends BaseNCodecOutputStream
    Provides Base32 encoding and decoding in a streaming fashion (unlimited size). When encoding the default lineLength is 76 characters and the default lineEnding is CRLF, but these can be overridden by using the appropriate constructor.

    The default behaviour of the Base32OutputStream is to ENCODE, whereas the default behaviour of the Base32InputStream is to DECODE. But this behaviour can be overridden by using a different constructor.

    Since this class operates directly on byte streams, and not character streams, it is hard-coded to only encode/decode character encodings which are compatible with the lower 127 ASCII chart (ISO-8859-1, Windows-1252, UTF-8, etc).

    • Constructor Detail

      • Base32OutputStream

        public Base32OutputStream(OutputStream out)
        Creates a Base32OutputStream such that all data written is Base32-encoded to the original provided OutputStream.
        Parameters:
        out - OutputStream to wrap.
      • Base32OutputStream

        public Base32OutputStream(OutputStream out,
                          boolean doEncode)
        Creates a Base32OutputStream such that all data written is either Base32-encoded or Base32-decoded to the original provided OutputStream.
        Parameters:
        out - OutputStream to wrap.
        doEncode - true if we should encode all data written to us, false if we should decode.
      • Base32OutputStream

        public Base32OutputStream(OutputStream out,
                          boolean doEncode,
                          int lineLength,
                          byte[] lineSeparator)
        Creates a Base32OutputStream such that all data written is either Base32-encoded or Base32-decoded to the original provided OutputStream.
        Parameters:
        out - OutputStream to wrap.
        doEncode - true if we should encode all data written to us, false if we should decode.
        lineLength - If doEncode is true, each line of encoded data will contain lineLength characters (rounded down to nearest multiple of 4). If lineLength <=0, the encoded data is not divided into lines. If doEncode is false, lineLength is ignored.
        lineSeparator - If doEncode is true, each line of encoded data will be terminated with this byte sequence (e.g. \r\n). If lineLength <= 0, the lineSeparator is not used. If doEncode is false lineSeparator is ignored.
