package: Inst
description: Model instantiation
RCS: $Id$
This module is responsible for instantiation of Modelica models.
The instantation is the process of instantiating model components,
flattening inheritance and generating equations from connect statements.
The instantiation process takes Modelica AST as defined in SCode and
produces variables and equations and algorithms, etc. as defined in DAE.
This module uses Lookup to lookup classes and variables from the
environment defined in Env. It uses Connect for generating equations from
connect statements. The type system defined in Types is used for
variable instantiation and type. DAE.Mod is used for modifiers and
merging of modifiers.
The extends language feature is performed by InstExtends. Instantiation of
algorithm sections and equation sections (including connections) is done
by InstSection.
There are basically four different ways/granularities of instantiation.
1. Using partialInstClassIn which only instantiates class definitions.
This function is used for looking up class definitions in e.g. packages.
For example, if looking up the class A.B.C, a new scope is opened and
A is partially instantiated in that scope using partialInstClassIn.
2. Function implicit instantiation. is the last argument of type bool to
instClassIn. It is needed since instantiation of functions is needed
to generate code for functions and there are cases where such
instantiations differ
from standard function instantiation. For example
function foo
input Real x{:};
...
end foo;
should be possible to instantiate even though the dimension size of x is
not known.
3. Implicit instantiation controlled by the next last argument to
instClassIn.
This is also needed, when a DAE should not be generated.
It is not clear when this is needed, perhaps it can be removed in the
future.
