using IPersistableElement [message #462990]

I am having some problems using the IPersistableElement interface.

I am using it for one of my classes which i would to save its state after
the workbench shutdowns. I just implemented the interface in that class and
created an IElementFactory for it (and the correspondent extension point).
However the saveState, getFactoryID, createElement methods are never called.

What ami i missing? does the IPersistableElement interface only work for
editors or special page inputs that the workbench knows or do i need to
register my object somewhere for the workbench know that it is persistable?

Thanks
Tiago

You have to call saveState after the workbench stops running (you can
register the workbench listener, for instance) and restoreState when
restoring your object.

Thanks Snjeza.

I see your point, however how can i get the memento from the workbench to
use for the IPersistableElement interface methods?

There is the ready API for views and editors (the saveState and init
methods).
If you want to use the Memento pattern for your classes, you have to
implement the IMemento interface.
See org.eclipse.ui.XMLMemento for details.
