SYNOPSIS

fedex_plus [ options ] [ express-file ]

Command Arguments:

options - see OPTIONS below

express-file - the name of an EXPRESS file

DESCRIPTION

fedex_plus is based on the NIST EXPRESS compiler fedex. fedex_plus translates an EXPRESS file into C++ code and a class library. The C++ library includes classes for representing all the types and entities in the input EXPRESS file, and a dictionary for describing those classes. The translation depends on base classes provided in the NIST STEP Class Library.

fedex_plus does not create C++ representations of the rules, procedures, or any EXPRESS constructs other than schemas, types and entities. It supports multiple schemas contained in a single file and complex entities. It generates code which can be integrated with orbix and ObjectStore.

Combined with the NIST STEP Class Library, the translator provides a "C++ working form" of an EXPRESS schema. fedex_plus was designed for use together with a graphical data editing system (see dataprobe(1)), but care has been taken to keep fedex_plus separate so that it can be used as a component of other software systems.

The fedex_plus compiler makes two passes through the EXPRESS file. In the first pass fedex_plus reads the syntax of the EXPRESS file and detects any errors. In the second pass fedex_plus converts the EXPRESS code into C++ source code. The C++ source code is generated in files in the directory in which fedex_plus was run. The files are named according to the schema names in the input EXPRESS file.

OPTIONS

-s|S Tells fedex_plus to use only single-inheritance, rather than multiple inheritance.
-c|C Generates C++ classes for use with CORBA (Orbix).
-l|L Prints logging code in the generated C++ classes.
-v Produces a version description.
-d Turns on debugging ("-d 0" describes this further).
-p<object>
  Turns on printing when processing certain objects, where <object> may be,
- e entity
- p procedure
- r rule
- f function
- t type
- s schema or file
- # pass #
- E everything (all of the above)
-w<warning>
  enable warning
-i<warning>
  disable warning, where <warning> may be,
- none
- all
- circular_subtype
- circular_select
- entity_as_type
- downcast
- unknown_subtype

If no arguments are given in the command line, a list and description of the options available are sent to stdout.

OUTPUT

fedex_plus sends the following to stdout subject to the options specified when executed:

- a statement indicating that the Express schema is being
compiled

- If errors in input encountered, a detailed list of errors
and/or warnings including
- filename
- line number
- description of error/warning

- If no errors encountered,
- a statement indicating that there were no errors
in input
- a statement indicating that the C++ source code
is being generated
- any warnings/errors detected while converting to
C++
