encapsulated package EvaluateParameter
" file: EvaluateParameter.mo
package: EvaluateParameter
description: EvaluateParameter contains functions to evaluated the bindexp of parameters with final=true or
annotation(Evaluate=true) and parameters which depent only on evaluated parameters
Concept:
traverse all parameter and get the parameters which must be evaluated O(N)
traverse the list and evaluate each parameter with a DFS O(N)
-> replacements for evaluated parameter
sort the parameters with tarjans algorithm O(N)
traverse the sorted parameters and replace in the bindexp the evaluated parameters
if a parameter have before a nonconstant bindexp and now a constant add it to the replacements
there are main function
- evaluate and replace parameters with final=true in variables and parameters
- evaluate and replace parameters with annotation(Evaluate=true) in variables and parameters
- evaluate and replace parameters with final=true or annotation(Evaluate=true) in variables and parameters
- evaluate and replace parameters with final=true in equations, variables and parameters
- evaluate and replace parameters with annotation(Evaluate=true) in equations, variables and parameters
- evaluate and replace parameters with final=true or annotation(Evaluate=true) in equations, variables and parameters
