public interface IPersistableElement extends IPersistable
This interface is typically included in interfaces where persistance is required.
When the workbench is shutdown objects which implement this interface
will be persisted. At this time the
is invoked to discover the id of the element factory that will be used
to re-create the object from a memento. Then the
method is invoked to store the element data into a newly created memento.
The resulting mementos are collected up and written out to a single file.
During workbench startup these mementos are read from the file. The
factory Id for each is retrieved and mapped to an
which has been registered in the element factory extension point. If a
factory exists for the Id it will be engaged to re-create the original
