TPTP - 4.1.0.1
Please explain with a simple example, as to what does the Inherited Base
Time and Inherited Cumulative time mean.
They are explained in the Help Contents, under the topic
Monitoring and analyzing application performance > Profiling an
application > Profiling Views > Using the Execution Statistics view

BUT
i could not understand properly as to what they meant.

ALSO,
How do i get these statistics. I'm able to get the Base time, avg base
time and the cumulative time but not the inherited times.

OK, I found how to do this part. But the earlier question remains

Hi Prince Singh,

Inherited base time is the amount of base time spent in an instance of a
class' methods plus the
amount of base time spent in any called methods that are part of the
hierarchy.

Inherited cumulative base time is the amount of base time spent in an
instance of a class' methods
plus the amount of base time spent in any called methods.


Here's an example to flesh out the concepts. Say that you have a package
named "mytestpackage",
and in that package there are four types: Grandparent, Parent, Child, and
Util.
Util is a sample utility class that any class might call.

// Code for Grandparent
package mytestpackage;

public class Grandparent {
protected Grandparent() { //1
}
}


// Code for Parent
package mytestpackage;

public class Parent extends Grandparent {
protected int counter;

protected Parent(int i) {
super(); //2
counter = i; //3
init(); //4
}

private void init() {
Util.readTime(counter); //5
}

public void run() {
Util.readTime(counter); //6
}
}



// Code for Child
package mytestpackage;

public class Child extends Parent {
public Child(int i) {
super(i); //7
Util.readTime2(i); //8
for(; i>=counter; i--) {
System.out.println("Hello from the child!"); //9
}
}

public static void main(String[] args) {
new Child(10); //10
}
}


In this example, the inherited base time of Child would be the time for
the call to super(i),
including any time for anything that super(i) calls in the
Grandparent/Parent/Child hierarchy:
Grandparent.Grandparent base time (//1)
+ Parent.init base time (//4 but not //5)
+ Parent.Parent base time (//3)


In this example, the inherited cumulative time of Child would be the time
for the call to super(i),
including any time for anything that super(i) calls, regardless of whether
that call is to a class
that's in the hierarchy or not:
Grandparent.Grandparent time (//1)
+ Parent.init time (//4 and //5)
+ Parent.Parent time (//3)
