Class IterableIteratorAdapter<T>

java.lang.Object
  de.lmu.ifi.dbs.elki.utilities.iterator.IterableIteratorAdapter<T>

Type Parameters:

T - object type

All Implemented Interfaces:

IterableIterator<T>, Iterable<T>, Iterator<T>

public final class IterableIteratorAdapter<T>
extends Object
implements IterableIterator<T>

for (Type var : new IterableIterator<Type>(iterator)) {
   // ...
 }
