Introduction
TPTP provides with not only a profiling framework Martini, but also several Java profilers. Call graph, memory and thread anlysis are three basic profiling scenarios.
Profilers Design Overview
To abstract common operations in diffrent profilers, a class named "CBaseProf" is added. The design pattern Template is used here. BaseProf defines several template methods and subclasses of it need to implement these template methods.
Besides BaseProf, profiling data will be stored for different profiling. We will discuss the data structure of them later. All these profiling data and handlers which point to components outside of profilers such as JPIAgent is stored in a profiling context class named "CProfEnv".
Different handler classes are added for process different Martini profiling events such as enter a method or a new thread start etc. These classes is packaged with concrete profilers.
