Detailed Description

Text-format-based persistence manager. This class implements a persistnece manager that reads and writes its objects in a human-readable text format. This is slow and objects get huge , but the format is clear and comprehensible - the ideal format to debug persistence-related programs. For production use, the XDRPersistenceManager is preferred.

Write an object header. This method write an object header. It starts with the current number of spaces needed for a correct indentation. If name is a null pointer, the object is a base object of the current object. This method then writes the string BASEOBJECT. If name is a name or an empty string, OBJECT is written.

Then, the object's type_name is written, followed by a blank, the character "@" to indicate an address and then the object's this pointer in decimal format. The last string in the line is either "-" (for a base object or an object without name) or the object's name.

The indentation level is incremented. Example for a base object: BASEOBJECT BALL::Composite @ 1145254238 - Example for a member object: BASEOBJECT BALL::Bond @ 2334208924 bond_
