 Description   

quickfix.Message.bodylength() returns a smaller value than quickfix.Message.toString().

This is because CTRL+A characters are not counted in the value of bodylength().

(If this is a feature and not a bug, it should be documented)

I mean quickfix.Message.toString().length()

Comment by Jörg Thönnes [ 01/Aug/08 ]

BodyLength is a Standard FIX Header tag. Its contents is defined in the FIX specification, e.g. FIX 4.4 Vol. 2, page 4:

> The message length is indicated in the BodyLength field and is verified by counting the number of characters in
> the message following the BodyLength field up to, and including, the delimiter immediately preceding the
> CheckSum tag ("10=").

So this value must differ from a plain toString().length(). And it is documented in the FIX spec.

Jörg,

The BodyLength FIELD you're talking about would be retrieved using:
BodyLength bodyLength = new BodyLength();
message.get(bodyLength);
int fixBodyLength = bodyLength.getValue();

I understand this to be different compared to Message.bodylength()?

Thanks

The m.bodyLength() value is the same as the tag 9 (BodyLength) in a fully constructed message. You also must retrieve tag 9 from the message header, not from the body.
