* Parameters used as input for the Collection <code>CertStore</code> |

|
35 |
* <p> |
|
36 |
* This class is used to provide necessary configuration parameters |
|
37 |
* to implementations of the Collection <code>CertStore</code> |
|
38 |
* algorithm. The only parameter included in this class is the |
|
39 |
* <code>Collection</code> from which the <code>CertStore</code> will |
|
40 |
* retrieve certificates and CRLs. |

* <p> |

* <b>Concurrent Access</b> |
|
43 |
* <p> |
|
44 |
* Unless otherwise specified, the methods defined in this class are not |
|
45 |
* thread-safe. Multiple threads that need to access a single |
|
46 |
* object concurrently should synchronize amongst themselves and |
|
47 |
* provide the necessary locking. Multiple threads each manipulating |
|
48 |
* separate objects need not synchronize. |
