IProject instanceof MyProject [message #491921]

Hello,
I am currently working on an eclipse plugin to create our own projects an debug them.
The project and file creation wizard is ready ready to use.
Now the problem is the following:
If I create a file with the fileCreationWizard I want to check whether the selected project is instanceof MyProject or not.
I don't really know how to check that.
A java project for example is a IJavaProject I think.
How can I create a IMyProject to check wheter IProject is instanceof IMyProject or not?

I would appreciate any help because I really don't know how to do that.

Great thanks!
Best regards
Alex

Alex,

It's not possible. Look at the Javadoc and you'll see

* @noimplement This interface is not intended to be implemented by clients.
* @noextend This interface is not intended to be extended by clients.

You should look at IProjectNature for better ways to "type" your projects.

Projects are distinguished by their "Types" using natures or facets (wtp) not by implementation class.

Facets are more powerful than natures in the sense that the latter can only "tag" your projects of certain type while the
former allows you to do certain actions while adding/removing the tag.

For more information on natures see

Thanks Ravi and Ed Merks, I read those articels and decided to add my own project nature.

Best regards,
