Hi!
There are no Field subclasses for Field for specific fieldsm like NoRelatedSym, MDReqID etc?
Is this intentionally, so you have to use new Field( , ) ?
Make the sources no very usable, I think? I wrote me a simple code generator in Python to create subclasses from a simple text file.
Maybe this costs some performance, but creates nicer sources?
Ciao,
Andreas
Have you benchmarked this against other implementation like http://fix8.org/
Hi!
I'm struggling with groups in messages at the moment. I guess it would be useful to write a Group class to make adding a group to a message more easy?
Ciao,
Andreas
Hi!
Thanks for your great work!
Maybe you could add 2 message types?
public static final MessageType OrderCancelRequest = new MessageType("F");
public static final MessageType MarketDataRequest = new MessageType("V");
I created a subclass of the MessageTypes just to add these 2. So I could remove this class.
I checked the code and see that recv() just return a empty Message. Is the method supposed to run or it's just a temp place holder?
Also the Session class are littered with System.out.println?
Hi,
In the recv() method(Session.java), parse a step message and get it's fields. The code is below:
while (rxBuf.position() < checksumOffset) {
int tag = Protocol.parseInt(rxBuf, (byte)'=');
ByteString value = Protocol.parseString(rxBuf, (byte)0x01);
fields.add(new Field(tag, value));
}
Maybe there is a bug in while loop:
parseString(ByteBuffer buf, byte delimiter) {
int start = buf.position();
for (;;) {
byte ch = buf.get();
if (ch == delimiter) {
break;
}
}
//buffer's posion is one after delimiter
//the end is pointer to delimiter
int end = buf.position() - 1;
buf.position(start);
return ByteString.of(buf, end-start);
}
after return ,the buffer's postion is pointer to delimiter. If next call parseInt(), the tag is error.
I think it should add rxBuf.get() before fields.add().
And I submit a SessionTest for this. Please check it. Thanks.
