Question

I have some questions about the registry.
We have

Preferences p = Preferences.userRoot();

If we execute

p.nodeExists("/HKEY_CURRENT_USER/Software/Policies/Microsoft")    

it will return true.
After it:

p = p.node("/HKEY_CURRENT_USER/Software/Policies");    
for(String s : p.childrenNames()){
    System.out.println(">" + s);
}

We see that it has one child: “Windows”. But

p.nodeExists("/HKEY_CURRENT_USER/Software/Policies/Microsoft/Windows")

returns false. Why?

Thanks.

UPDATE

Ok. I have some mistakes. Let me try again: Why does

p.nodeExists("/HKEY_CURRENT_USER/Software/Policies/Microsoft/Windows") 

return false?

Answer 1

If you execute the code lines shown, in the order shown, when you get to the line

p.nodeExists("/HKEY_CURRENT_USER/Software/Policies/Microsoft/Windows")

p does not anymore point to the user root, but to “/HKEY_CURRENT_USER/Software/Policies”.

Btw you have a probable omission in your third code sample:

p = p.node("/HKEY_CURRENT_USER/Software/Policies");    

should be

p = p.node("/HKEY_CURRENT_USER/Software/Policies/Microsoft");
