Analyzing performance with a call graph model

You use the PowerScript functions and PocketBuilder objects listed in Table 26-8 to analyze the performance of an application. You can use these functions only on the desktop.

**Table 26-8: Functions for analyzing performance**
Use this function	With this object	To do this
SetTraceFileName	Profiling	Set the name of the trace file to be analyzed.
BuildModel	Profiling	Build a call graph model based on the trace file. You can pass optional parameters that let you track the progress of the build.
RoutineList	Profiling and ProfileClass	Get a list of routines in the model or in a class.
ClassList	Profiling	Get a list of classes in the model.
SystemRoutine	Profiling	Get the name of the routine node that represents the root of the model.
IncomingCallList	ProfileRoutine	Get a list of routines that called a specific routine.
OutgoingCallList	ProfileRoutine and ProfileLine	Get a list of routines called by a specific routine or from a specific line.
LineList	ProfileRoutine	Get a list of lines in the routine in line order.
DestroyModel	Profiling	Destroy the current performance analysis model and all the objects associated with it.

Each of these functions returns a value of the enumerated datatype ErrorReturn. The objects contain information such as the number of times a line or routine was executed, and the amount of time spent in a line or routine and in any routines called from that line or routine.
