| * A specification of <code>CertStore</code> parameters. |
| * <p> |
| * The purpose of this interface is to group (and provide type safety for) |
| * all <code>CertStore</code> parameter specifications. All |
| * <code>CertStore</code> parameter specifications must implement this |
| * interface. |
| * <p> |
| * Typically, a <code>CertStoreParameters</code> object is passed as a parameter |
| * to one of the {@link CertStore#getInstance CertStore.getInstance} methods. |
| * The <code>getInstance</code> method returns a <code>CertStore</code> that |
| * is used for retrieving <code>Certificate</code>s and <code>CRL</code>s. The |
| * <code>CertStore</code> that is returned is initialized with the specified |
| * parameters. The type of parameters needed may vary between different types |
| * of <code>CertStore</code>s. |
| * |
| * @see CertStore#getInstance |

| /** |
| * Makes a copy of this <code>CertStoreParameters</code>. |
| * <p> |
| * The precise meaning of "copy" may depend on the class of |
| * the <code>CertStoreParameters</code> object. A typical implementation |
| * performs a "deep copy" of this object, but this is not an absolute |
| * requirement. Some implementations may perform a "shallow copy" of some |
| * or all of the fields of this object. |
| * <p> |
| * Note that the <code>CertStore.getInstance</code> methods make a copy |
| * of the specified <code>CertStoreParameters</code>. A deep copy |
| * implementation of <code>clone</code> is safer and more robust, as it |
| * prevents the caller from corrupting a shared <code>CertStore</code> by |
| * subsequently modifying the contents of its initialization parameters. |
| * However, a shallow copy implementation of <code>clone</code> is more |
| * appropriate for applications that need to hold a reference to a |
| * parameter contained in the <code>CertStoreParameters</code>. For example, |
| * a shallow copy clone allows an application to release the resources of |
| * a particular <code>CertStore</code> initialization parameter immediately, |
| * rather than waiting for the garbage collection mechanism. This should |
| * be done with the utmost care, since the <code>CertStore</code> may still |
| * be in use by other threads. |
| * <p> |
| * Each subclass should state the precise behavior of this method so |
| * that users and developers know what to expect. |
