Glue Class TDataSet
The main class supporting STAR framework is a TDataSet. It was developed in STAR with name StDataSet. Later accepted in ROOT as TDataSet. The class is simple, and very similar to UNIX directory/file system.
- Everything important for framework is inherited from TDataSet. Tables,StEvent,i/o branches and modules==makers are inherited from TDataSet.
- STAR framework structure is a TDataSet tree, where all framework objects are placed, in some specific order. This structure contains the data objects and the methods(makers) together;
- From the ROOT prompt, user can browse them and can invoke the methods of each object manually. It is very important for debugging and understanding the structure.
