The Line Timing Filters page allows you to set specific classes, methods and functions to be included in, or excluded from, the line hooking process.

 

 

These settings are identical to the Class And Function filters in the previous section, except they only affect the line timing hooks.

 

Since line-timed functions are controlled independently from other functions being monitored in a session, you can time just the lines within a single function or a single method in a class without the overhead of line-timing everything else.

 

These filters apply only to the DLLs and files that you have not already excluded via other filters.

 

 

Listing what to exclude or include

 

By default, Performance Validator will try to hook lines in all classes, methods and functions in the hooked files, but you can choose to list only those which should be included or excluded.

 

•Hook all... hook everything (the default)

 

•Only hook ... hook only the classes, methods and functions listed
 

If not line timing everything (which has a performance overhead), this would be the typical case, i.e. to selectively line-time only your areas of interest
 

•Don't hook ... hook everything except the classes, methods and functions listed
 

Line timing filters can also be added via the instrumentation filter options on the context menus of each main tab. See more on the Statistics menu for example.

 

 

Managing the list

 

Choose from known methods:

 

•Add... shows the Class::Method Browser dialog below

 

Type or choose a class and/or method from the pre-populated drop-down list of all functions:
 

 

When typing an entry, you'll see a message at the bottom of the dialog if the symbol doesn't exist:

 

 

 

Choose from known methods:

 

•Add List... shows the List of classes or functions dialog below

 

Enter any number of plain class::method or function names or just paste them in.

 

 

The list will not be validated against known functions. Do not include return types, brackets, parameters or other details.

 

Remove items as normal:

 

•Remove removes selected items in the list
 

•Remove All removes all items, clearing the list

 

Alternatively, press to delete selected items, and + to select all items in the list first.

 

 

Exporting and importing

 

Since the list can be quite complicated to set up, you can export the settings to a file and import them again later. This is useful when switching between different target applications.

 

•Export... choose or enter a filename Save outputs the filtered list to the file
 

•Import... navigate to an existing *.pvxc file Open loads the filtered list

 

The exported file can be used with the -classAndFunctionFile command line option.
