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 TCint::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()

 TDataType dtor deletes adopted CINT TypedefInfo object.

const char * GetTypeName(EDataType type)

 Return the name of the type.

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.

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; }
