Examples of org.apache.gora.mapreduce.FakeResolvingDecoder

org.apache.gora.mapreduce.FakeResolvingDecoder
Avro uses a ResolvingDecoder which resolves two schemas and converts records written by one to the other, and validates the input. However, Gora needs to write extra information along with the data, so the validation is not consistent with the grammer generated by Avro. So we need to fake the ResolvingDecoder (which is sadly hard codec into GenericDatumReader) until we can write our own GrammerGenerator extending ResolvingGrammerGenerator of avro.


  protected ResolvingDecoder getResolvingDecoder(Decoder decoder)
  throws IOException {
    ResolvingDecoder resolvingDecoder = decoderCache.get(decoder);
    if(resolvingDecoder == null) {
      resolvingDecoder = new FakeResolvingDecoder(rootSchema, decoder);
      decoderCache.put(decoder, resolvingDecoder);
    }
    return resolvingDecoder;
  }
