Direct Known Subclasses:

```
public abstract class CRL
extends Object

This class is an abstraction of certificate revocation lists (CRLs) that have different formats but important common uses. For example, all CRLs share the functionality of listing revoked certificates, and can be queried on whether or not they list a given certificate.
Specialized CRL types can be defined by subclassing off of this abstract class.
