package: Static
description: Static analysis of expressions
RCS: $Id$
This module does static analysis on expressions.
The analyzed expressions are built using the
constructors in the `Exp\' module from expressions defined in \'Absyn\'.
Also, a set of properties of the expressions is calculated during analysis.
Properties of expressions include type information and a boolean indicating if the
expression is constant or not.
If the expression is constant, the \'Ceval\' module is used to evaluate the expression
value. A value of an expression is described using the \'Values\' module.
The main function in this module is evalExp which takes an Absyn.Exp and transform it
into an DAE.Exp, while performing type checking and automatic type conversions, etc.
To determine types of builtin functions and operators, the module also contain an elaboration
handler for functions and operators. This function is called elabBuiltinHandler.
NOTE: These functions should only determine the type and properties of the builtin functions and
operators and not evaluate them. Constant evaluation is performed by the Ceval module.
The module also contain a function for deoverloading of operators, in the \'deoverload\' function.
It transforms operators like \'+\' to its specific form, ADD, ADD_ARR, etc.
Interactive function calls are also given their types by elabExp, which calls
elabCallInteractive.
Elaboration for functions involve checking the types of the arguments by filling slots of the
argument list with first positional and then named arguments to find a matching function. The
details of this mechanism can be found in the Modelica specification.
The elaboration also contain function deoverloading which will be added to Modelica in the future."
