/** |
|
44 |
* The policy for a Java runtime (specifying |
|
45 |
* which permissions are available for code from various principals) |
|
46 |
* is represented as a separate |
|
47 |
* persistent configuration. The configuration may be stored as a |
|
48 |
* flat ASCII file, as a serialized binary file of |
|
49 |
* the Policy class, or as a database. <p> |
|
50 |
* |
|
51 |
* <p>The Java runtime creates one global Policy object, which is used to |
|
52 |
* represent the static policy configuration file. It is consulted by |
|
53 |
* a ProtectionDomain when the protection domain initializes its set of |
|
54 |
* permissions. <p> |
|
55 |
* |
|
56 |
* <p>The Policy <code>init</code> method parses the policy |
|
57 |
* configuration file, and then |
|
58 |
* populates the Policy object. The Policy object is agnostic in that |
|
59 |
* it is not involved in making policy decisions. It is merely the |
|
60 |
* Java runtime representation of the persistent policy configuration |
|
61 |
* file. <p> |
|
62 |
* |
|
63 |
* <p>When a protection domain needs to initialize its set of |
|
64 |
* permissions, it executes code such as the following |
|
65 |
* to ask the global Policy object to populate a |
|
66 |
* Permissions object with the appropriate permissions: |
|
67 |
* <pre> |
|
68 |
* policy = Policy.getPolicy(); |
|
69 |
* Permissions perms = policy.getPermissions(MyCodeSource) |
|
70 |
* </pre> |
|
71 |
* |
|
72 |
* <p>The protection domain passes in a CodeSource |
|
73 |
* object, which encapsulates its codebase (URL) and public key attributes. |
|
74 |
* The Policy object evaluates the global policy in light of who the |
|
75 |
* principal is and returns an appropriate Permissions object. |
|
76 |
* |
|
77 |
* @deprecated As of JDK 1.4, replaced by |
|
78 |
* {@link sun.security.provider.PolicyParser}. |
|
79 |
* This class is entirely deprecated. |
