Interface DoubleDBIDList

All Superinterfaces:

DBIDs

All Known Subinterfaces:

public interface DoubleDBIDList
extends DBIDs

Collection of double values associated with objects. To iterate over the results, use the following code:

 
 for (DoubleDBIDListIter iter = result.iter(); iter.valid(); iter.advance()) {
   // You can get the distance via: iter.doubleValue();
   // And use iter just like any other DBIDRef
 }
 
 

If you are only interested in the IDs of the objects, the following is also sufficient:

 
 for (DBIDIter iter = result.iter(); iter.valid(); iter.advance()) {
   // Use iter just like any other DBIDRef
 }
