|
30 |
* have different formats but important common uses. For example, all CRLs
|
|
|
31 |
* share the functionality of listing revoked certificates, and can be queried
|
|
|
32 |
* on whether or not they list a given certificate.
|

33 |
* <p>
|
|
|
34 |
* Specialized CRL types can be defined by subclassing off of this abstract
