Areas of Interest - Categorization rules
This chapter describes the rules used for dividing profiling results into different areas of interest.
Method tagging - how it is done
The main principle is tagging selected methods with marks specifiyng the areas the methods belong to. When processing call context tree of profiling results each method is queried for its tags and assigned to areas accordingly. A not tagged method is assigned to areas specified by tags of the first preceding tagged method.
Methods may be tagged by:
- Tagging the whole package and all subpackages
- Tagging all the methods of a specific class
- Tagging only a particular method of a particular class
- Tagging all implementors of a particular interface
- Tagging all subclasses of a particular class
- Free-type tagging - using all available information like thread name or time spent in the method
