TTreeResult
Class defining interface to a TTree query result with the same
interface as for SQL databases. A TTreeResult is returned by
TTree::Query() (actually TTreePlayer::Query()).
Related classes are TTreeRow.
TTreeResult()
Create a query result object.
TTreeResult(Int_t nfields)
Create a query result object.
~TTreeResult()
Cleanup result object.
void Close(Option_t *)
Close query result.
Bool_t IsValid(Int_t field)
Check if result set is open and field index within range.
Int_t GetFieldCount()
Get number of fields in result.
const char* GetFieldName(Int_t field)
Get name of specified field.
TSQLRow* Next()
Get next query result row. The returned object must be
deleted by the user and becomes invalid when the result set is
closed or deleted.
void AddField(Int_t field, const char *fieldname)
Add field name to result set. This is an internal method that is not
exported via the abstract interface and that should not be user called.
void AddRow(TSQLRow *row)
Adopt a row to result set. This is an internal method that is not
exported via the abstract interface and that should not be user called.
