Examples of DatumReader

    String recordJson =
      "{\"type\":\"record\", \"name\":\"Foo\", \"fields\":[{\"name\":\"f\", "
    +"\"type\":"+schemaJson+", "
    +"\"default\":"+defaultJson+"}]}";
    Schema expected = Schema.parse(recordJson);
    DatumReader in = new GenericDatumReader(ACTUAL, expected);
    GenericData.Record record = (GenericData.Record)
      in.read(null, new BinaryDecoder(new ByteArrayInputStream(new byte[0])));
    assertEquals("Wrong default.", defaultValue, record.get("f"));
    assertEquals("Wrong toString", expected, Schema.parse(expected.toString()));
  }

Examples of org.apache.avro.io.DatumReader


  private List<Object> fromJson(Schema schema, File file) throws Exception {
    InputStream in = new FileInputStream(file);
    List<Object> data = new ArrayList<Object>();
    try {
      DatumReader reader = new GenericDatumReader(schema);
      Decoder decoder = DecoderFactory.get().jsonDecoder(schema, in);
      while (true)
        data.add(reader.read(null, decoder));
    } catch (EOFException e) {
    } finally {
      in.close();
    }
    return data;
