//! To optimise processing (e.g. firstly bind an Entity to a Module

  //!
  //! According to the cases, dispatch can either

  //! Prepares an entity to be deleted. What does it mean :
  //! Basically, any class of entity may define its own destructor
  //! By default, it does nothing but calling destructors on fields
  //! With the Memory Manager, it is useless to call destructor,
  //! it is done automatically when the Handle is nullified(cleared)
  //! BUT this is ineffective in looping structures (whatever these
  //! are "Implied" references or not).
  //!
  //! THUS : if no loop may appear in definitions, a class which
  //! inherits from TShared is correctly managed by automatic way
  //! BUT if there can be loops (or simply back pointers), they must
  //! be broken, for instance by clearing fields of one of the nodes
  //! The default does nothing, to be redefined if a loop can occur
  //! (Implied generally requires WhenDelete, but other cases can
  //! occur)
  //!
  //! Warning : <dispatched> tells if the entity to be deleted has been
  //! produced by Dispatch or not. Hence WhenDelete must be in
  //! coherence with Dispatch
  //! Dispatch can either copy or not.
  //! If it copies the entity, this one should be deleted
  //! If it doesnt (i.e. duplicates the handle) nothing to do
  //!

  //! Warning : While this string may be edited on the spot, if it is a read
  //! field, the returned value must be copied before.
