@IntegerType field serialization byte array is correct?

[scmp99]

import org.indunet.fastproto.FastProto;
import org.indunet.fastproto.annotation.type.IntegerType;
import java.nio.ByteBuffer;
import java.util.Arrays;

public class FastProtoTest {
@IntegerType(0)
private int nameLen = 5;

public static void main(String[] args) {
// Output results: [5, 0, 0, 0]
System.out.println(Arrays.toString(FastProto.toByteArray(new FastProtoTest())));
// toByteArray and parseFrom is right.
System.out.println(
FastProto.parseFrom(FastProto.toByteArray(new FastProtoTest()), FastProtoTest.class)
.nameLen);
// Output results: [0, 0, 0, 5]
System.out.println(Arrays.toString(ByteBuffer.allocate(4).putInt(5).array()));
}
}

FastProto uses little endian by default, but ByteBuffer uses big endian.
If you want to use big endian, there are two ways.

1. All fields are big endian

    import org.indunet.fastproto.annotation.Endian;
    
    @Endian(EndianPolicy.BIG)
    public class FastProtoTest {
    ...
    }

2. Only field value is big endian.

import org.indunet.fastproto.annotation.Endian;

public class FastProtoTest {
  @Endian(EndianPolicy.BIG)
  int value = 5;
}

Thanks for your attention.
FastProto is undergoing a major version change, version 4.0 will ensure simple api, clearer data types, and higher efficiency.

Thanks for the reply. Got it.
