Data Structures

class IFSelect_GeneralModifier

This class gives a frame for Actions which modify the effect
of a Dispatch, i.e. :
By Selections and Dispatches, an original Model can be
splitted into one or more "target" Models : these Models
contain Entities copied from the original one (that is, a
part of it). Basically, these dispatched Entities are copied
as identical to their original counterparts. Also the copied
Models reproduce the Header of the original one.

Modifiers allow to change this copied content : this is the
way to be used for any kind of alterations, adaptations ...
They are exploited by a ModelCopier, which firstly performs
the copy operation described by Dispatches, then invokes the
Modifiers to work on the result.

Each GeneralModifier can be attached to :

all the Models produced
a Dispatch (it will be applied to all the Models obtained
from this Dispatch) designated by its Ident in a ShareOut
in addition, to a Selection (facultative) : this adds a
criterium, the Modifier is invoked on a produced Model only
if this Model contains an Entity copied from one of the
Entities designated by this Selection.
(for special Modifiers from IFAdapt, while they must work on
definite Entities, this Selection is mandatory to run)

Remark : this class has no action attached, it only provides
a frame to work on criteria. Then, sub-classes will define
their kind of action, which can be applied at a precise step
of the production of a File : see Modifier, and in the
package IFAdapt, EntityModifier and EntityCopier
