Class Description

 Class defining interface to a row of a TTree query result.           
 Objects of this class are created by TTreeResult methods.            
 Related classes are TTreeResult.                                     

TTreeRow(Int_t nfields)
 Single row of a query result.

TTreeRow(TSQLRow *original)
 This is a shallow copy of a real row, i.e. it only contains
 a pointer to the original.

 Destroy row object.

void Close(Option_t *)
 Close row.

Bool_t IsValid(Int_t field)
 Check if row is open and field index within range.

ULong_t GetFieldLength(Int_t field)
 Get length in bytes of specified field.

const char* GetField(Int_t field)
 Get specified field from row (0 <= field < GetFieldCount()).

void AddField(Int_t field, const char *fieldvalue)
 Add field value to row. This is an internal method that is not
 exported via the abstract interface and that should not be user called.
