Gephi

Problem with developed plugin when update Gephi

Asked by Luis Manuel Correas Ramos

Hi!

First of all, sorry but my english is really poor.

I developed a couple months ago a module for network simulation scenarios exporting. I worked with alpha 0.4 version of Gephi and the plugin executes perfectly. But the problem is when I update Gephi, project doesn't compile. I get the following:

and much more...

If I export plugin to a nbm file and I install on the application, I can open the plugin interface, but results don't appear, plugin doesn't work, but no errors are produced.

Really thanks for all.

Hi, that is because the Export API changed, as it was not in his final version.

You can track API changes in the overview.html file int he source code (you see it here: http://bazaar.launchpad.net/~gephi.team/gephi/0.7/annotate/head%3A/overview.html)

Here is the paragraph that should concern you:

"Export API refactoring, inspired from ImportAPI. Create an ExporterBuilder interface for exporter creation and different exporters: GraphExporter, VectorExporter, ByteExporter and CharacterExporter that covers common cases. The way exporters write data has been rationalized by using either java.io.Writer (text) or java.io.OutputStream (byte). The ExportController has been improved to support all use-cases, including file, writer and stream export. "

So you have to adapt your plugin code to be compatible with the 0.7beta, let me know if you need some guidance.

Really thanks Mathieu.

Could you help me a bit? I'm lost now.

I have three classes that implements interface TextFileExporter. What changes do I need to adapt to new situation?
