// TDataSet //
// //
// TDataSet class is to create a special compound object-container: //
// //
// ==================================================================== //
// TDataSet object ::= the "named" list of TDataSet objects //
// ==================================================================== //
// where the "list" (the pointer to TList object) may contain no object //
// //
// TDataSet object has a back pointer to its "parent" TDataSet //
// object, the "character" *name* and "character" *title* //
// //
// The service this class does provide is to help the user to build //
// and manage the hierarchy of his/her data but the data itself. //
// //
// So it is not "Container" itself rather the basement (base class) //
// to built the containers. //
// //
// One may derive the custom container classes from TDataSet. //
// See for example TObjectSet, TTable, TVolume, TFileSet //
// These classes derived from TDataSet: //
// //
// Class Name //
// ---------- //
// TObjectSet::public TDataSet - is a container for TObject //
// TTable::public TDataSet - is a container for the array //
// of any "plain" C-structure //
// TNode::public TDataSet - is a container for 3D objects //
// TMaker:: public TDataSet - is a container for STAR "control" //
// objects //
// etc etc //
// //
// TDataSet class is a base class to implement the directory-like //
// data structures and maintain it via TDataSetIter class iterator //
// //
// TDataSet can be iterated using an iterator object (see TDataSetIter) //
// or by TDataSet::Pass method (see below) //
// //
// Terms: Dataset - any object from the list above //
// ===== Member is called "DataSet Member" //
// //
// Structural - the "Dataset Member" is its //
// member "Structural member" if its "back pointer" //
// points to this object //
// //
// Dataset - we will say this TDataSet object "OWNs" //
// Owner (or is an OWNER / PARENT of ) another //
// (parent) TDataSet object if the last one is its //
// "Structural Member" //
// //
// Associated - If some object is not "Structural member" //
// member of this object we will say it is an //
// "Associated Member" of this dataset //
// //
// Orphan - If some dataset is a member of NO other //
// dataset TDataSet object it is called an "orphan" //
// dataset object //
// //
// - Any TDataSet object may be "Owned" by one and only one another //
// TDataSet object if any. //
// //
// - Any TDataSet object can be the "Structural Member" of one and //
// only one another TDataSet //
// //
// - Any TDataSet object may be an "Associated Member" for any number //
// of other TDataSet objects if any //
// //
// - NAME issue: //
// Each "dataset member" is in possession of some "alpha-numerical" //
// NAME as defined by TNamed class. //
// The NAME may contain any "printable" symbols but "SLASH" - "/" //
// The symbol "RIGHT SLASH" - "/" can not be used as any part of the //
// "DataSet Member" NAME //
// Any DataSet can be found by its NAME with TDataSetIter object //
// //
// - TITLE issue: //
// Each "dataset member" is in possession of the "alpha-numerical" //
// TITLE as defined by TNamed class. The meaning of the TITLE is //
// reserved for the derived classes to hold there some indetification //
// that is special for that derived class. //
// //
// This means the user must be careful about the "TDataSet //
// NAME and TITLE since this may cause some "side effects" of the //
// particular class functions //
// //
// - It is NOT required those all "DataSet Members" are in possession //
// of the unique names, i.e. any number of "DataSet Members" //
// may bear one and the same name //
// //
// Actions: //
// ======== //
// Create DataSet is born either as "Orphan" or //
// as "Structural Member" //
// of another TDataSet object //
// //
// Add One dataset can be included into another dataset. //
// Upon adding: //
// - the "Orphan dataset" becomes "Structural Member" //
// - "Structural Members" of another dataset becomes the //
// "Associated Member" of this datatset //
// //
// Delete - Upon deleting the "Structural Member": //
// - "REMOVES" itself from the "Parent DataSet". //
// - Its "Associated memberships" is not changed though //
// //
// The last means the DataSet with the "Associated Members"//
// may contain a DIED pointers to unexisting "Associated" //
// objects !!! //
// //
// Further information is provided my the particular method //
// descriptions. //
// //
// The TDataSet class has several methods to control object('s) //
// memberships //
