class TClassTable: public TObject


This class registers for all classes their name, id and dictionary
function in a hash table. Classes are automatically added by the
ctor of a special init class when a global of this init class is
initialized when the program starts (see the ClassImp macro).

Function documentation

TClassTable()

 TClassTable is a singleton (i.e. only one can exist per application).

~TClassTable()

 TClassTable singleton is deleted in Terminate().

void Print(Option_t* option = "") const

 Print the class table. Before printing the table is sorted
 alphabetically. Only classes specified in option are listed.
 The default is to list all classes.
 Standard wilcarding notation supported.

char * At(int index)

 Returns class at index from sorted class table. Don't use this iterator
 while modifying the class table. The class table can be modified
 when making calls like TClass::GetClass(), etc.
 Returns 0 if index points beyond last class name.

int Classes()

{ return fgTally; }

void Init()

{ fgCursor = 0; SortTable(); }

void Add(const char* cname, Version_t id, const type_info& info, VoidFuncPtr_t dict, Int_t pragmabits)

 Add a class to the class table (this is a static function).

void Remove(const char* cname)

 Remove a class from the class table. This happens when a shared library
 is unloaded (i.e. the dtor's of the global init objects are called).

TClassRec * FindElementImpl(const char* cname, Bool_t insert)

 Find a class by name in the class table (using hash of name). Returns
 0 if the class is not in the table. Unless arguments insert is true in
 which case a new entry is created and returned.

TClassRec * FindElement(const char* cname, Bool_t insert = kFALSE)

 Find a class by name in the class table (using hash of name). Returns
 0 if the class is not in the table. Unless arguments insert is true in
 which case a new entry is created and returned.

Version_t GetID(const char* cname)

 Returns the ID of a class.

Int_t GetPragmaBits(const char* name)

 Returns the pragma bits as specified in the LinkDef.h file.

VoidFuncPtr_t GetDict(const char* cname)

 Given the class name returns the Dictionary() function of a class
 (uses hash of name).

VoidFuncPtr_t GetDict(const type_info& info)

 Given the type_info returns the Dictionary() function of a class
 (uses hash of type_info::name()).

char * Next()

 Returns next class from sorted class table. Don't use this iterator
 while modifying the class table. The class table can be modified
 when making calls like TClass::GetClass(), etc.

void PrintTable()

 Print the class table. Before printing the table is sorted
 alphabetically.

void SortTable()

 Sort the class table by ascending class ID's.

void Terminate()

 Deletes the class table (this static class function calls the dtor).
