returns the pointer the "next" TDataSet object = 0 if all objects have been returned.

mode = kContinue - default normal mode kPrune - stop passing of the current branch but continue with the next one if any kUp - break passing, return to the previous level, then continue all other - are treated as "kContinue"

◆ Notify() [1/2]

virtual Bool_t TDataSetIter::Notify ( )

This method must be overridden to handle object notification.

Reimplemented from TObject.

Reimplemented in TVolumeViewIter.

◆ Notify() [2/2]

void TDataSetIter::Notify ( TDataSet dataset)
virtual

Notify(TDataSet *dataset)

This dummy method is called when TDataSetIter::Find dives in "dataset" to look for thew next level of the dataset's printf("void TDataSetIter::Notify(TDataSet *) level: %d %s\n",fDepth,ds->GetName());

◆ operator[]()

TDataSet * TDataSetIter::operator[] ( const Char_t path)
virtual

operator [] returns the pointer to the TDataSet if it does contain any data (TTable for example)

Input: path = The path to the dataset to find

Output: pointer to the dataset if it found and its TDataSet::HasData() method returns non-zero (see for example TTable::HasData() )

◆ Rmdir() [1/2]

Remove the TDataSet *dataset from the current dataset If the current dataset is the deleted dataset the its parent becomes the "current dataset" or 0 if this dataset has no parent.

returns: the "current dataset" pointer
