Chronicle Queue : How to have declare a object that is to be persisted with one of the field as byte[]

[Lata]

Hi,

I am using ChronicleQueue. I have to persist a object that has multiple fields and byte[] is one of the field in the object. The object that I have to persist is:

public interface Event extends Byteable {

boolean compareAndSwapOwner(int expected, int value);

int getOwner();

void setOwner(int meta);

void setId(long id);

long getId();

void setType(long id);

long getType();

void setTimestamp(long timestamp);

long getTimestamp();

byte[] getBytes();

　

void setBytes(@MaxSize(8) byte[] bytes);

}

When I run my test code to create the queue the above object, I am getting following error for byte[] field

Exception in thread "main" java.lang.RuntimeException: java.lang.IllegalArgument
Exception: type must be an interface, was class [B

Want to know what is the right way to declare a byte[] field for persisting in queue

Thanks,

Lata

Hello Lata,

The generated data values don't support byte[] at the moment.  If you want to write this data I suggest you write it directly to the queue.

appender.startExcerpt();

appender.writeInt(owner);

appender.writeLong(id);

appender.writeLong(type);

appender.writeLong(timestamp);

appender.write(bytes);

appender.finish();

To read you do the same but with tailer.readXXX

Regards,

   Peter.
