Class Children
Apr 23rd, 2006, 6:55am  
Hello,

I am currious wether there is a way for classes constructed within another class to access variables held within the class that it is constructed within. For example, I need a class to hold dynamic variables that other classes can access and change, without creating duplicates of that variable within itself and returning back and forth. Mainly becuase the variavle i want to store and change are massive arrays.

Can anyone suggest a neat method that does not involve using the instant name of the parent class.

cheers,
Benjamin

If the child class is actually defined as a child class, it can just access it's parent's variables at will.

e.g. Quote:
class top
{
 String a;
 child b;
 top()
 {
   a="top";
   b=new child();
 }
 
 void print()
 {
   b.print();
 }

 class child
 {
   child()
   {
   }
   
   void print()
   {
     println(a);
   }
 }
}

void setup()
{
 size(200,200);
 top a=new top();
 a.print();
}

Thanks. Shortly after posting my quiry I found the answer in the java documentation. We have been spoiled with Tabs in processing so whenever I define a new class I start a new Tab. Thank you for your help.
