Customizing the database layout

5.2.1 The pfx file

The description file that is called using the -roption, the so-called pfx file, handles the specification of class-wide attribute names.

The attribute names used for the mapping to the database consist of the following compo- nents:

classPrefix_attributCounter_extension

classPrefix

is the part of the field name that is common to all fields in a class. Neither does inheritance change it, i.e. it has the same value in the subclass as in the superclass. It can be specified by the user with the help of the description file specified below.

When using identical views, this prefix is used to generate the attribute names of both the table and also the view belonging to the class.

attributCounter and extension are always created by mgen2.

Layout of the description file

The description file consists of formatted lines with the following line format.

classname prefix

Classname

represents a valid C++ identifier.

prefix

represents a valid SQL identifier. The prefix entries must differ for all classes and can be a maximum of 6 characters in length.

Please note that all entries in the description file are case-sensitive.

If no prefix is found for a specific class, it is automatically generated by the mgen2 gener- ator. The created prefixes have the following format:

Xdddd or Xddddd with d=0,1,2,..,9

The generation starts at Xdddd=X1024 or Xmmmm, where mmmm represents the highest value for dddd+1 found in the description file. That means that if X10200 was found in the description file, the generation starts at X10201.

Once prefixes have been specified by the mgen2 for all classes, both those found in the description file and the newly generated prefixes are output to the specified description file. The old version of the pfx file is first backed up to a file with the extension .bak. An empty or non-existent description file can be specified for use in the creation of the first description file.
