The modules are implemented as a class and the parameter (input or output) might have different types from module to module. The references is stored as Object.

module mod1 = new module(firstInput);
 
mod1.input == 1
mod2.output == 0
 
module mod2 = new module(mod1.output);
 
mod2.input == 0
mod2.output == 0
 
mod1.compute(2);
 
mod1.input == 1
mod1.ouptut == 3
 
mod2.compute(3);
 
mod2.input == 0
mod2.output == 3

public Module(Object* source)

I dont think I have made it clear that I want the input to be like a pointer in C++,

What I would like to know is “Would I be better off to place the string manipulations into separate constructors, methods, or maybe lumping them all together in either one”.

<code>
void watcher_Changed(object sender, FileSystemEventArgs e)

	// TODO: Make sure that this is the only handler running on these files

	string[] fileList = Directory.GetFiles(Path.GetDirectoryName(e.FullPath), "*.xml");
	foreach (string file in fileList)
