Interface DoubleDBIDListIter

All Superinterfaces:

ArrayIter, DBIDArrayIter, DBIDIter, DBIDRef, DoubleDBIDIter, Iter

All Known Subinterfaces:

DoubleDBIDListMIter, DoubleIntegerDBIDListIter, DoubleIntegerDBIDListMIter

All Known Implementing Classes:

DoubleIntegerDBIDArrayList.Itr, DoubleIntegerDBIDSubList.Itr, IntegerDBIDKNNSubList.Itr

public interface DoubleDBIDListIter
extends DoubleDBIDIter, DBIDArrayIter

Iterator over Double+DBID pairs results.

There is no getter for the DBID, as this implements DBIDRef.
