| /** |
| * A <code>CRLSelector</code> that selects <code>X509CRLs</code> that |
| * match all specified criteria. This class is particularly useful when |
| * selecting CRLs from a <code>CertStore</code> to check revocation status |
| * of a particular certificate. |
| * <p> |
| * When first constructed, an <code>X509CRLSelector</code> has no criteria |
| * enabled and each of the <code>get</code> methods return a default |
| * value (<code>null</code>). Therefore, the {@link #match match} method |
| * would return <code>true</code> for any <code>X509CRL</code>. Typically, |
| * several criteria are enabled (by calling {@link #setIssuers setIssuers} |
| * or {@link #setDateAndTime setDateAndTime}, for instance) and then the |
| * <code>X509CRLSelector</code> is passed to |
| * {@link CertStore#getCRLs CertStore.getCRLs} or some similar |
| * method. |
| * <p> |
| * Please refer to <a href="http://www.ietf.org/rfc/rfc3280.txt">RFC 3280: |
| * Internet X.509 Public Key Infrastructure Certificate and CRL Profile</a> |
| * for definitions of the X.509 CRL fields and extensions mentioned below. |
| * <p> |
| * <b>Concurrent Access</b> |
| * <p> |
| * Unless otherwise specified, the methods defined in this class are not |
| * thread-safe. Multiple threads that need to access a single |
| * object concurrently should synchronize amongst themselves and |
| * provide the necessary locking. Multiple threads each manipulating |
| * separate objects need not synchronize. |
