Access a Network parameter

[De]

I have created a cSimpleModule class in my simulation and I am trying
to access a parameter created in the network part of the ned file.
Simply using the par() function doesn't work because that tries to
access parameters from the corresponding module in the ned file. But I
want something from the network. Is there a way I can do this?

C++ file:

GoodGuy::GoodGuy(){
...
// ***These are the values I want access to***
numG = par("numGood");
numB = par("numBad");
}

NED file:

simple GoodGuy{
gates:
input port @directin @loose;
}

network Lizzy{
parameters:

// ***These are the parameters in the network***
// ***See how I need them in the network scope here.***

int numGood @prompt("Number of good guys?");
int numBad = intuniform(0,numGood);

submodules:
G[numGood]: GoodGuy;
B[numBad]: BadGuy ;
}

Btw, I know this looks like a lot of code to read, but the code isn't
necessary to answer my question. It's just there for clarifications.

Hi,

 

You can either use :

 

numG = getParentModule()->par("numGood");

 

This has to be adapted depending on your topology...

 

or use the first upper level module holding the parameter you are looking for :

 

numG = getAncestorPar(("numGood");

Thank you for the suggestion but it gave me a runtime error. I think
because those options are still looking for the values in module
parameters, but the ones I want are in the network parameters. And
I've yet to find any methods to get to network parameters.

I tried grouping some things into a compound module and then using the
methods you suggested but then things messed up with the prompt
messages.

simulation.getSystemModule()->par("bla");

system module == the toplevel module in the model == "the network"

Thanks, I think that worked. My program is still finicky, but I think
that's a separate issue.

Thank You both again, you're always very helpful.
