NonNullSingletonIterator (com.ibm.wala.util 1.5.2 API)

java.lang.Object
- com.ibm.wala.util.collections.NonNullSingletonIterator<T>

All Implemented Interfaces:

java.util.Iterator<T>
```
public class NonNullSingletonIterator<T>
extends java.lang.Object
implements java.util.Iterator<T>
```
A singleton iterator for an object which is guaranteed to be not-null. Exploiting this invariant allows this class to be slightly more efficient than Collections.iterator()
