Example 1 with ReflectionSchemaGenerator

use of io.cdap.cdap.internal.io.ReflectionSchemaGenerator in project cdap by caskdata.

the class RecordWithString method testEnum.

@Test
public void testEnum() throws IOException, UnsupportedTypeException {
    PipedOutputStream output = new PipedOutputStream();
    PipedInputStream input = new PipedInputStream(output);
    Schema schema = new ReflectionSchemaGenerator().generate(TestEnum.class);

    BinaryEncoder encoder = new BinaryEncoder(output);
    writer.encode(TestEnum.VALUE1, encoder);
    writer.encode(TestEnum.VALUE3, encoder);
    writer.encode(TestEnum.VALUE2, encoder);
    BinaryDecoder decoder = new BinaryDecoder(input);
    Schema readSchema = Schema.parseJson(schema.toString());
    ReflectionDatumReader<TestEnum> reader = new ReflectionDatumReader<>(readSchema, TypeToken.of(TestEnum.class));
    Assert.assertEquals(TestEnum.VALUE1, reader.read(decoder, readSchema));
    Assert.assertEquals(TestEnum.VALUE3, reader.read(decoder, readSchema));
    Assert.assertEquals(TestEnum.VALUE2, reader.read(decoder, readSchema));
}
