| * Parameters used as input for the PKIX <code>CertPathValidator</code> |
| * algorithm. |
| * <p> |
| * A PKIX <code>CertPathValidator</code> uses these parameters to |
| * validate a <code>CertPath</code> according to the PKIX certification path |
| * validation algorithm. |
| * |
| * <p>To instantiate a <code>PKIXParameters</code> object, an |
| * application must specify one or more <i>most-trusted CAs</i> as defined by |
| * the PKIX certification path validation algorithm. The most-trusted CAs |
| * can be specified using one of two constructors. An application |
| * can call {@link #PKIXParameters(Set) PKIXParameters(Set)}, |
| * specifying a <code>Set</code> of <code>TrustAnchor</code> objects, each |
| * of which identify a most-trusted CA. Alternatively, an application can call |
| * {@link #PKIXParameters(KeyStore) PKIXParameters(KeyStore)}, specifying a |
| * <code>KeyStore</code> instance containing trusted certificate entries, each |
| * of which will be considered as a most-trusted CA. |
| * <p> |
| * Once a <code>PKIXParameters</code> object has been created, other parameters |
| * can be specified (by calling {@link #setInitialPolicies setInitialPolicies} |
| * or {@link #setDate setDate}, for instance) and then the |
| * <code>PKIXParameters</code> is passed along with the <code>CertPath</code> |
| * to be validated to {@link CertPathValidator#validate |
| * CertPathValidator.validate}. |
| * <p> |
| * Any parameter that is not set (or is set to <code>null</code>) will |
| * be set to the default value for that parameter. The default value for the |
| * <code>date</code> parameter is <code>null</code>, which indicates |
| * the current time when the path is validated. The default for the |
| * remaining parameters is the least constrained. |
| * <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. |
