Ok, I've been thinking about this one, and I think:
first, the offset and length fields are good to have, yes? If they're not useful, then they should certainly not be included. But I think that for applications that transfer a lot of data, it will be useful, as you can use one large byte[] and don't have to either use small byte[]s for your main data buffer.
I also think they can be useful.
second, the default case should most certainly be that the user doesn't have to set either field (offset or length). To that end, I think that auto-setting offset and length when the setData() method is called is the 'right' thing to do. For users that don't care about offset/length, they don't do a thing - it's handled for them. For the few users that do want to set offset and/or length, all they have to know is they must set the offset and/or length _after_ the data, not before. That's not too bad, and it allows correct behavior in the default (i.e. 99% of the time) case.I'd rather have setData(data) that uses offset 0, and length data.length and a setData(data, offset, length) than separate setPfset and setLength methods.
So...I'm going to update the Javadoc and default implementation to reflect this, unless there are comments.
Everything's coming together I think, I'd like to put a 0.10 package out tomorrow or this weekend...so let me know if there are API comments (or RI comments, but the API is more important to get right at this point).I have two problems, I keep getting a lot of NullPointerExceptions from the javax-usb-ri/src/com/ibm/jusb/UsbEndpointImp.java there the wrapped UsbEndpoint is null.
Also, when just getting the topology from my hubs and my printer everything works fine, but when connecting my Xanboo box the JVM dies due to a signal 11 in the native code and I'm trying to resolve why.
