ARText - Formula Language
The AUTOSAR formula language is a general purpose expression language
(first specified in AUTOSAR 4.0). The language can be used at several points
within the AUTOSAR methodology, for example for specifying and evaluating
binding constraints at variation points. The ARText formula language
implementation provides a human-readable representation of the XML-based
AUTOSAR formulas. Furthmore, it supports the evaluation of formulas as well
as static type checking. The formula language will be available with the
release of Artop 3.0.
Bi-directional conversion from and to XML
AUTOSAR formulas are serialized as XML mixed text, which is not intended to
be edited by humans. The ARText implementation provides a bi-directional
conversion mechanism, which allows the user to edit formulas in a human
readable representation which is then directly converted into AUTOSAR XML
(and vice versa).
The formula language has different primitive types (integer, double,...).
The Artext-based editor supports static type checking to avoid type errors
The ARText-based implementation of the formula language provides an
interpreter that supports all features of the AUTOSAR formula language. The
interpreter enables on-the-fly evaluation of formulas, which, for example,
can be used for evaluating variants in AUTOSAR models.
