How to compute the metric Response for a Method with NDepend

Question

Is there any way to get the number of "source code lines" that could result from calling nested function?

For this question my example:

Selection of functions

Function name	Lines of Code (LOC) [function body]
Function1	10
Function2	20
Function3	20

Example 1
Function1
...|-> calls Function2
......|-> calls Function3
Sum of LOC= 50

Example 2
Function1
...|-> calls Function3
......|-> calls Function2
Sum of LOC= 50

Example 3
Function1
..|-> calls Function2
..|-> calls Function3
..|-> calls Function2
Sum of LOC= 70

Answer 1

Here is a code query that computes the Response for each method of a code base:

from m  in Application.Methods

let methodsCalledMetric =
   m.MethodsCalled.FillIterative(
       methods => methods.SelectMany(mm => mm.MethodsCalled))

let methodsCalled = methodsCalledMetric.DefinitionDomain

let responseLoc = methodsCalled.Sum(mm => mm.NbLinesOfCode)

select new { m, methodsCalled, responseLoc } 

The result looks like:

The set of methods called by any method can be either listed (by clicking the 136 methods cell for example) or exported to the dependency graph to visualize it in a clearer way:
