Examples with EitherTypeInfo org.apache.flink.api.java.typeutils.EitherTypeInfo used on opensource projects

Example 1 with EitherTypeInfo

use of org.apache.flink.api.java.typeutils.EitherTypeInfo in project flink by apache.

the class EitherSerializerTest method testSerializeIndividually.

@Test
public void testSerializeIndividually() throws IOException {
    EitherTypeInfo<LongValue, DoubleValue> eitherTypeInfo = new EitherTypeInfo<>(ValueTypeInfo.LONG_VALUE_TYPE_INFO, ValueTypeInfo.DOUBLE_VALUE_TYPE_INFO);
    EitherSerializer<LongValue, DoubleValue> eitherSerializer = (EitherSerializer<LongValue, DoubleValue>) eitherTypeInfo.createSerializer(new ExecutionConfig());
    LongValue lv = new LongValue();
    DoubleValue dv = new DoubleValue();
    Either<LongValue, DoubleValue> left = Left(lv);
    Either<LongValue, DoubleValue> right = Right(dv);
    TestOutputView out = new TestOutputView();
    eitherSerializer.serialize(left, out);
    eitherSerializer.serialize(right, out);
    eitherSerializer.serialize(left, out);
    TestInputView in = out.getInputView();
    // the first deserialization creates a new instance of Left
    Either<LongValue, DoubleValue> copy0 = eitherSerializer.deserialize(right, in);
    // then the cross-references are used for future copies
    Either<LongValue, DoubleValue> copy1 = eitherSerializer.deserialize(copy0, in);
    Either<LongValue, DoubleValue> copy2 = eitherSerializer.deserialize(copy1, in);
    // validate reference equality
    assertSame(right, copy1);
    assertSame(copy0, copy2);
    // validate reference equality of contained objects
    assertSame(right.right(), copy1.right());
    assertSame(copy0.left(), copy2.left());
}

    EitherTypeInfo<Tuple2<LongValue, LongValue>, DoubleValue> eitherTypeInfo = new EitherTypeInfo<>(new TupleTypeInfo<Tuple2<LongValue, LongValue>>(ValueTypeInfo.LONG_VALUE_TYPE_INFO, ValueTypeInfo.LONG_VALUE_TYPE_INFO), ValueTypeInfo.DOUBLE_VALUE_TYPE_INFO);
    EitherSerializer<Tuple2<LongValue, LongValue>, DoubleValue> eitherSerializer = (EitherSerializer<Tuple2<LongValue, LongValue>, DoubleValue>) eitherTypeInfo.createSerializer(new ExecutionConfig());
