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

TDataType(const char *typenam) : fInfo(0), fProperty(kIsFundamental)
 Constructor for basic data types, like "char", "unsigned char", etc.

 TDataType dtor deletes adopted G__TypedefInfo object.

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

const char* GetFullTypeName() const
 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) const
 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() const
 Get property description word. For meaning of bits see EProperty.

void SetType(const char *name)
 Set type id depending on name.

Int_t Size() const
 Get size of basic typedef'ed type.

void CheckInfo()
 Refresh the underlying information.
