Extracting information from the call graph model

After you have built a call graph model of the application, you can extract detailed information from it.

For routines and lines, you can extract the timing information shown in Table 26-9 from the ProfileRoutine and ProfileLine objects.

**Table 26-9: Timing information in the call graph model**
Property	What it means
AbsoluteSelfTime	The time spent in the routine or line itself. If the routine or line was executed more than once, this is the total time spent in the routine or line itself.
MinSelfTime	The shortest time spent in the routine or line itself. If the routine or line was executed only once, this is the same as AbsoluteSelfTime.
MaxSelfTime	The longest time spent in the routine or line itself. If the routine or line was executed only once, this is the same as AbsoluteSelfTime.
AbsoluteTotalTime	The time spent in the routine or line and in routines or lines called from the routine or line. If the routine or line was executed more than once, this is the total time spent in the routine or line and in called routines or lines.
MinTotalTime	The shortest time spent in the routine or line and in called routines or lines. If the routine or line was executed only once, this is the same as AbsoluteTotalTime.
MaxTotalTime	The longest time spent in the routine or line and in called routines or lines. If the routine or line was executed only once, this is the same as AbsoluteTotalTime.
PercentSelfTime	AbsoluteSelfTime as a percentage of the total time tracing was active.
PercentTotalTime	AbsoluteTotalTime as a percentage of the total time tracing was active.

Example: extracting information from a call graph model

The following function extracts information from a call graph model about the routines called from a specific routine. You would use similar functions to extract information about the routines that called the given routine and about the routine itself.

The function takes a ProfileCall object and an index as arguments and returns a structure containing the number of times the called routine was executed and execution times for the called routine.

str_func_detail lstr_result
ProfileClass lproclass_class
ProfileRoutine lprort_routine

// get the name of the called routine
// from the calledroutine property of
// the ProfileCall object passed to the function
lprort_routine = a_pcall.Calledroutine
lstr_result.Name = ""
lproclass_class = a_pcall.Class
IF isValid(lproclass_class) THEN &
   lstr_result.Name += lproclass_class.Name + "."
lstr_result.name += a_pcall.Name

lstr_result.hits = a_pcall.HitCount
lstr_result.selfTime = a_pcall. &
   AbsoluteSelfTime * timeScale
lstr_result.totalTime = a_pcall. &
   AbsoluteTotalTime * timeScale
lstr_result.percentSelf = a_pcall.PercentSelfTime
lstr_result.percentTotal= a_pcall.PercentTotalTime
lstr_result.index = al_index

RETURN lstr_result
