Class Description

                                                                      //                                                                      
 Basic data type descriptor (datatype information is obtained from    
 CINT). This class describes the attributes of type definitions       
 (typedef's). The TROOT class contains a list of all currently        
 defined types (accessible via TROOT::GetListOfTypes()).

TDataType(G__TypedefInfo *info)

 Default TDataType ctor. TDataTypes are constructed in TROOT via
 a call to TCint::UpdateListOfTypes().

TDataType(const char *typenam)

 Constructor for basic data types, like "char", "unsigned char", etc.

TDataType(const TDataType& dt)

copy constructor

TDataType& operator=(const TDataType& dt)

assignement operator

~TDataType()

 TDataType dtor deletes adopted G__TypedefInfo object.

const char * GetTypeName(EDataType type)

 Return the name of the type.

const char * GetTypeName()

 Get basic type of typedef, e,g.: "class TDirectory*" -> "TDirectory".
 Result needs to be used or copied immediately.

const char * GetFullTypeName()

 Get full type description of typedef, e,g.: "class TDirectory*".

EDataType GetType(const type_info &typeinfo)

 Set type id depending on name.

const char * AsString(void *buf)

 Return string containing value in buffer formatted according to
 the basic data type. The result needs to be used or copied immediately.

Long_t Property()

 Get property description word. For meaning of bits see EProperty.

void SetType(const char *name)

 Set type id depending on name.

Int_t Size()

 Get size of basic typedef'ed type.

void CheckInfo()

 Refresh the underlying information.

Int_t GetType()
