|
|

|
|
* When first constructed, an {@code X509CRLSelector} has no criteria

* would return {@code true} for any {@code X509CRL}. Typically,
|
|
* several criteria are enabled (by calling {@link #setIssuers setIssuers}
|
|
* or {@link #setDateAndTime setDateAndTime}, for instance) and then the
|
|
* {@code X509CRLSelector} is passed to
|
|
* {@link CertStore#getCRLs CertStore.getCRLs} or some similar
|
|
* method.
|
