All Implemented Interfaces:

java.util.Enumeration
```
class ClassEnumeration
extends java.lang.Object
implements java.util.Enumeration
```
An enumeration that filters only classes from the enumeration of the class pool. Code has been added to also include classes referenced in method and field signatures.
