Interface MigrationHandler

public interface MigrationHandler
Migrate a tcomp data instance from one version to another one. This uses a flat format to make any conversion very easy and an "untyped" structure to avoid
  • to require the type to be passed through the layers
  • to require to instantiate unknown objects
This is linked to a component through Version to ensure cross inputs can be handled.
