  - iterator
```
public java.util.Iterator<Reference> iterator()
```
    Specified by:
    
    iterator in interface java.lang.Iterable<Reference>
  - isWellDefined
```
protected boolean isWellDefined()
```
    Determines if the variable for this reference collection is "well-defined." A variable is well-defined if we can prove at compile-time that it's assigned a value before it's used.
    Notice that if this function returns false, this doesn't imply that the variable is used before it's assigned. It just means that we don't have enough information to make a definitive judgment.
