class ReportEntity from Interface inherits TShared
---Purpose : A ReportEntity is produced to aknowledge and memorize the
-- binding between a Check and an Entity. The Check can bring
-- Fails (+ Warnings if any), or only Warnings. If it is empty,
-- the Report Entity is for an Unknown Entity.
--
-- The ReportEntity brings : the Concerned Entity, the
-- Check, and if the Entity is empty (Fails due to Read
-- Errors, hence the Entity could not be loaded), a Content.
-- The Content is itself an Transient Object, but remains in a
-- literal form : it is an "Unknown Entity". If the Concerned
-- Entity is itself Unknown, Concerned and Content are equal.
--
-- According to the Check, if it brings Fail messages,
-- the ReportEntity is an "Error Entity", the Concerned Entity is
-- an "Erroneous Entity". Else it is a "Correction Entity", the
-- Concerned Entity is a "Corrected Entity". With no Check
-- message and if Concerened and Content are equal, it reports
-- for an "Unknown Entity".
--
-- Each norm must produce its own type of Unknown Entity, but can
-- use the class UndefinedContent to brings parameters : it is
-- enough for most of information and avoids to redefine them,
-- only the specific part remains to be defined for each norm.

is
Create (unknown : mutable Transient) returns mutable ReportEntity;
---Purpose : Creates a ReportEntity for an Unknown Entity : Check is empty,
-- and Concerned equates Content (i.e. the Unknown Entity)
Create (acheck : Check; concerned : mutable Transient)
returns mutable ReportEntity;
---Purpose : Creates a ReportEntity with its features :
-- - <acheck> is the Check to be memorised
-- - <concerned> is the Entity to which the Check is bound
-- Later, a Content can be set : it is required for an Error
SetContent (me : mutable; content : mutable Transient);
---Purpose : Sets a Content : it brings non interpreted data which belong
-- to the Concerned Entity. It can be empty then loaded later.
-- Remark that for an Unknown Entity, Content is set by Create.
Check (me) returns Check;
---Purpose : Returns the stored Check
---C++ : return const &
CCheck (me : mutable) returns Check;
---Purpose : Returns the stored Check in order to change it
---C++ : return &
Concerned (me) returns mutable Transient;
---Purpose : Returns the stored Concerned Entity. It equates the Content
-- in the case of an Unknown Entity
HasContent (me) returns Boolean;
---Purpose : Returns True if a Content is stored (it can equate Concerned)
HasNewContent (me) returns Boolean;
---Purpose : Returns True if a Content is stored AND differs from Concerned
-- (i.e. redefines content) : used when Concerned could not be
-- loaded
Content (me) returns mutable Transient;
---Purpose : Returns the stored Content, or a Null Handle
-- Remark that it must be an "Unknown Entity" suitable for
-- the norm of the containing Model
IsError (me) returns Boolean;
---Purpose : Returns True for an Error Entity, i.e. if the Check
-- brings at least one Fail message
IsUnknown (me) returns Boolean;
---Purpose : Returns True for an Unknown Entity, i,e. if the Check
-- is empty and Concerned equates Content
