class TDataType: public TDictionary

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()).

Function documentation

TDataType(TypedefInfo_t* info = 0)
 Default TDataType ctor. TDataTypes are constructed in TROOT via
 a call to TCling::UpdateListOfTypes().
TDataType(const char* typenam)
 Constructor for basic data types, like "char", "unsigned char", etc.
TDataType(const TDataType& )
copy constructor
TDataType& operator=(const TDataType& )
assignement operator
 TDataType dtor deletes adopted CINT TypedefInfo object.
const char * GetTypeName(EDataType type)
 Return the name of the type.
TString GetTypeName()
 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.
void AddBuiltins(TCollection* types)
 Create the TDataType objects for builtins.
TDataType* GetDataType(EDataType type)
 Given a EDataType type, get the TDataType* that represents it.
Int_t GetType() const
{ return (Int_t)fType; }
