net.fec.openrq.encoder.DataEncoder

A RaptorQ encoder for a data object.

An encoder receives a data object (source data) and produces encoding packets (as specified in RFC 6330). The source data is divided into a fixed number of source blocks, and each source block can be encoded independently.

An encoder provides a {@link SourceBlockEncoder} object per source block, and each takes care of actually encodingthe source data into encoding packets. These encoder objects are accessed via the method {@link #sourceBlock(int)}, or the method {@link #sourceBlockIterable()}.

The number of source blocks, the length of the source data and other parameters are specified as the FEC parameters. The method {@link #fecParameters()} provides the associated parameters to the encoder.

    @Parameters(name = "{0}")
    public static Iterable<Object[]> getSBDInfos() {


        final List<Object[]> list = new ArrayList<>();


        final DataEncoder dataEnc = OpenRQ.newEncoder(new byte[FEC_PARAMS.dataLengthAsInt()], FEC_PARAMS);
        final DataDecoder dataDec = OpenRQ.newDecoder(FEC_PARAMS, 0);


        for (SourceBlockDecoder sbDec : dataDec.sourceBlockIterable()) {
            // insert empty decoder
            list.add(new Object[] {sbDec.information(), true});
        }


        for (SourceBlockEncoder sbEnc : dataEnc.sourceBlockIterable()) {
            final int K = sbEnc.numberOfSourceSymbols();
            final SourceBlockDecoder sbDec = dataDec.sourceBlock(sbEnc.sourceBlockNumber());


            for (int n = 0; n < K / 3; n++) {
                final EncodingPacket pac = sbEnc.sourcePacket(n);
