- All Superinterfaces:
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
getFactoryId method is invoked to
discover the id of the element factory that will be used to re-create the
object from a memento. Then the
saveState 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
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 object.
