14// Class for xml code generation
15// It should be used for generation of xml streamers, which could be used outside root
16// environment. This means, that with help of such streamers user can read and write
17// objects from/to xml file, which later can be accepted by ROOT.
18//
19// At the moment supported only classes, which are not inherited from TObject
20// and which not contains any TObject members.
21//
22// To generate xml code:
23//
24// 1. ROOT library with required classes should be created.
25// In general, without such library non of user objects can be stored and
26// retrieved from any ROOT file
27//
28// 2. Generate xml streamers by root script like:
29//
30// void generate() {
31// gSystem->Load("libRXML.so"); // load ROOT xml library
32// gSystem->Load("libuser.so"); // load user ROOT library
33//
34// TList lst;
35// lst.Add(TClass::GetClass("TUserClass1"));
36// lst.Add(TClass::GetClass("TUserClass2"));
37// ...
38// TXMLPlayer player;
39// player.ProduceCode(&lst, "streamers"); // create xml streamers
40// }
41//
42// 3. Copy "streamers.h", "streamers.cxx", "TXmlFile.h", "TXmlFile.cxx" files
43// to user project and compile them. TXmlFile class implementation can be taken
44// from http://web-docs.gsi.de/~linev/xmlfile.tar.gz
45//
46// TXMLPlayer class generates one function per class, which called class streamer.
47// Name of such function for class TExample will be TExample_streamer.
48//
49// Following data members for streamed classes are supported:
50// - simple data types (int, double, float)
51// - array of simple types (int[5], double[5][6])
52// - dynamic array of simple types (int* with comment field // [fSize])
53// - const char*
54// - object of any nonROOT class
55// - pointer on object
56// - array of objects
57// - array of pointers on objects
58// - stl string
59// - stl vector, list, deque, set, multiset, map, multimap
60// - allowed arguments for stl containers are: simple data types, string, object, pointer on object
61// Any other data member can not be (yet) read from xml file and write to xml file.
62//
63// If data member of class is private or protected, it can not be accessed via
64// member name. Two alternative way is supported. First, if for class member fValue
65// exists function GetValue(), it will be used to get value from the class, and if
66// exists SetValue(), it will be used to set appropriate data member. Names of setter
67// and getter methods can be specified in comments filed like:
68//
69// int fValue; // *OPTION={GetMethod="GetV";SetMethod="SetV"}
70//
71// If getter or setter methods does not available, address to data member will be
72// calculated as predefined offset to object start address. In that case generated code
73// should be used only on the same platform (OS + compiler), where it was generated.
74//
75// Generated streamers resolve inheritance tree for given class. This allows to have
76// array (or vector) of object pointers on some basic class, while objects of derived
77// class(es) are used.
78//
79// To access data from xml files, user should use TXmlFile class, which is different from
80// ROOT TXMLFile, but provides very similar functionality. For example, to read
81// object from xml file:
82//
83// TXmlFile file("test.xml"); // open xml file
84// file.ls(); // show list of keys in file
85// TExample* ex1 = (TExample*) file.Get("ex1", TExample_streamer); // get object
86// file.Close();
87//
88// To write object to file:
89//
90// TXmlFile outfile("test2.xml", "recreate"); // create xml file
91// TExample* ex1 = new TExample;
92// outfile.Write(ex1, "ex1", TExample_streamer); // write object to file
93// outfile.Close();
94//
95// Complete example for generating and using of external xml streamers can be taken from
96// http://www-docs.gsi.de/~linev/xmlreader.tar.gz
97//
98// Any bug reports and requests for additional functionality are welcome.
