A SessionFile is intended to manage access between a WorkSession and an Ascii Form, to be considered as a Dump. It allows to write the File from the WorkSession, and later read the File to the WorkSession, by keeping required descriptions (such as dependances).

A SessionFile is intended to manage access between a WorkSession and an Ascii Form, to be considered as a Dump. It allows to write the File from the WorkSession, and later read the File to the WorkSession, by keeping required descriptions (such as dependances).
The produced File is under an Ascii Form, then it may be easily consulted. It is possible to cumulate reading of several Files. But in case of Names conflict, the newer Names are forgottens.
The Dump supports the description of XSTEP functionalities (Sharing an Interface File, with Selections, Dispatches, Modifiers ...) but does not refer to the Interface File which is currently loaded.
SessionFile works with a library of SessionDumper type objects
The File is Produced as follows : SessionFile produces all general Information (such as Int and Text Parameters, Types and Inputs of Selections, Dispatches, Modifiers ...) and calls the SessionDumpers to produce all the particular Data : creation arguments, parameters to be set It is Read in the same terms : SessionFile reads and interprets all general Information, and calls the SessionDumpers to recognize Types and for a recognized Type create the corresponding Object with its particular parameters as they were written. The best way to work is to have one SessionDumper for each consistent set of classes (e.g. a package).
