Defines basic File Access Module, under the control of
IGESReaderTool for Reading and IGESWriter for Writing :
Specific actions concern : Read and Write Own Parameters of
an IGESEntity.
The common parts (Directory Entry, Lists of Associativities
and Properties) are processed by IGESReaderTool & IGESWriter
Each sub-class of ReadWriteModule is used in conjunction with
a sub-class of Protocol from IGESData and processes several
types of IGESEntity (typically, them of a package) :
The Protocol gives a unique positive integer Case Number for
each type of IGESEntity it recognizes, the corresponding
ReadWriteModule processes an Entity by using the Case Number
to known what is to do
On Reading, the general service NewVoid is used to create an
IGES Entity the first time
Warning : Works with an IGESReaderData which stores "DE parts" of Items

| virtual Standard_Boolean | NewRead (const Standard_Integer casenum, const Handle< Interface_FileReaderData > &data, const Standard_Integer num, Handle< Interface_Check > &ach, Handle< Standard_Transient > &ent) const |
Specific operator (create+read) defaulted to do nothing. <br>
It can be redefined when it is not possible to work in two <br>
steps (NewVoid then Read). This occurs when no default <br>
constructor is defined : hence the result <ent> must be <br>
created with an effective definition from the reader. <br>
Remark : if NewRead is defined, Copy has nothing to do. <br>
