Class InitialisationManager

java.lang.Object
  uk.co.weft.configurator.InitialisationManager

public abstract class InitialisationManager

extends java.lang.Object

Central broker for initialisation checkers. There's a serious problem with initialising a new webapp in place after it's been delivered. We need to do this to set up database structures and possibly in future for other reasons as well, in order to make webapps extremely simple to deliver. But firstly it's quite difficult to come up with a scheme for checking for 'virginity' which will work in all circumstances, and secondly as the check will be made each time a servlet is initialised it has to be fast. TODO: doesn't really work and probably isn't going to. Should be deleted.
