deferred class SpecificModule  from IGESData  inherits Transient

    ---Purpose : This class defines some Services which are specifically
    --           attached to IGES Entities : Dump

uses IGESEntity, IGESDumper,
     Messenger from Message

is

    OwnDump (me; CN : Integer; ent : IGESEntity;
    	      dumper : IGESDumper;  S : Messenger from Message; own : Integer)
	is deferred;
    ---Purpose : Specific Dump for each type of IGES Entity : it concerns only
    --           own parameters, the general data (Directory Part, Lists) are
    --           taken into account by the IGESDumper
    --           See class IGESDumper for the rules to follow for <own> and
    --           <attached> level

    OwnCorrect (me; CN : Integer; ent : mutable IGESEntity)
    	returns Boolean  is virtual;
    ---Purpose : Specific Automatic Correction on own Parameters of an Entity.
    --           It works by setting in accordance redundant data, if there are
    --           when there is no ambiguity (else, it does nothing).
    --           Remark that classic Corrections on Directory Entry (to set
    --           void data) are taken into account alsewhere.
    --           
    --           For instance, many "Associativity Entities" have a Number of
    --           Properties which must have a fixed value.
    --           Or, a ConicalArc has its Form Number which records the kind of
    --           Conic, also determined from its coefficients
    --           But, a CircularArc of which Distances (Center-Start) and
    --           (Center-End) are not equal cannot be corrected ...
    --           
    --           Returns True if something has been corrected in <ent>
    --           By default, does nothing. If at least one of the Types
    --           processed by a sub-class of SpecificModule has a Correct
    --           procedure attached, this method can be redefined
