Class Description


 Default ctor.

TStreamerElement(const char *name, const char *title, Int_t offset, Int_t dtype, const char *typeName) : TNamed(name,title)
 Create a TStreamerElement object.

 TStreamerElement dtor.

Bool_t CannotSplit() const
returns true if the element cannot be split, false otherwise
An element cannot be split if the corresponding class member
has the special characters "||" as the first characters in the comment field

TClass* GetClassPointer() const
returns a pointer to the TClass of this element

Int_t GetExecID() const
returns the TExec id for the EXEC instruction in the comment field
of a TRef data member

const char* GetFullName() const
 return element name including dimensions, if any
 Note that this function stores the name into a static array.
 You should may be copy the result.

Int_t GetSize() const
returns size of this element in bytes

TMemberStreamer* GetStreamer() const

const char* GetTypeNameBasic() const
return type name of this element
in case the type name is not a standard basic type, return
the basic type name known to CINT

void Init(TObject *)

Bool_t IsOldFormat(const char *newTypeName)
The early 3.00/00 and 3.01/01 versions used to store
dm->GetTypeName instead of dm->GetFullTypename
if this case is detected, the element type name is modified

Bool_t IsBase() const

void ls(Option_t *) const

void SetArrayDim(Int_t dim)
 Set number of array dimensions.

void SetMaxIndex(Int_t dim, Int_t max)
set maximum index for array with dimension dim

void SetStreamer(TMemberStreamer *streamer)
set pointer to Streamer function for this element

void Streamer(TBuffer &R__b)
 Stream an object of class TStreamerElement.

void Update(const TClass *oldClass, TClass *newClass)
function called by the TClass constructor when replacing an emulated class
by the real class
