Ok, I've changed the methods:

startDate(Date d) --> startValue(Object o)
endDate(Date d) --> endValue(Object o)

Then, in the DynamicEntityWriter class, I check if the Object "o" is a istance of the chosen type in the timeformat attribute, otherwise an exception is thrown.

Now, would you like to test it before publishing? I've done some tests, but if somebody wants to contribute... you're welcome.

Maybe it needs to create a google code project... what do you think of that?

Bye,
Francesco Ficarola

Uhm... I'm not sure if we're talking about the same concept. Before changing code again, I need to know if I've understood what you've meant.

First possibility:
I have a date (Date object in java) and I have to convert it to an integer (i.e., epoch timestamp, like this: http://www.epochconverter.com/). If this is the case, what kind of conversion should I use for double?

Second possibility:
I've just got a number (e.g., 234 or 123.45678) and simply put it in start(open)/end(open) attributes.

Which is the case, the first one or the second one?

Thank you,
Francesco Ficarola

Ah ok, so it can be any number, like a "user-timestamp". I'll fix that.

Ok, I've finished these changes:

- "timetype" attribute is renamed to "timeformat".
- and "slice" are renamed and "spell" correspondingly.
- Now the "timeformat" can be integer, double (default), date, dateTime
- Open intervals (non-inclusive) are added: "startopen" and "endopen" attributes.
- Bug fix on all "Attribute setTitle(String title)": the expression in checkArgument was wrong.

Now, how do we organize the update?

Bye,

Yes it is.

Ok, so the integer part is the year, while the decimal part is the month.

Good, thanks.

Hi,

I've almost completed the changes, but I have to implement timeformat in DOUBLE and INTEGER form (date and dateTime are done).
I haven't found anything on GEXF schema... What's their official form? E.g., 2012 for integer and 2012.04 for double?

Thanks,
Francesco

Hi,

since yesterday I've worked on gexf4j source to change it in according to latest version of GEXF draft, that is 1.2 (Gephi 0.8 compatible).

I'll let you know when I finish the changes.

Francesco

[SOLVED] gexf4j and spells

2012-04-13T17:21:59+01:00

Hi everybody,

I'm working on a parser to transform a file from "log-style" to a GEXF graph. Then I'd like to import that graph into Gephi 0.8. In order to build the GEXF file I'm using the gexf4j library. Unfortunately I've noticed that there's nothing for the "spell" attribute. I've just found a "Slice" class, but the history of Gephi (http://gexf.net/format/history.html) says that slice are renamed to spell... so, I want to be consistent with the last version of Gephi.

What should I use?

Thank you for your help.

Regards,
Francesco
