| <div class="block">Interface that a security manager or policy provider can optionally | |
| implement in order to support the saving and restoring of custom security | |
| context state. If the installed security manager or policy provider | |
| implements this interface, then its <code>getContext</code> method is | |
| delegated to by the corresponding method of the | |
| <a href="../../../../net/jini/security/Security.html" title="class in net.jini.security"><code>Security</code></a> class, with precedence given to the | |
| security manager. | |
| <p> | |
| This interface is intended to be implemented by security managers and policy | |
| providers whose security contexts include state in addition to that provided | |
| by <a href="http://docs.oracle.com/javase/6/docs/api/java/security/AccessControlContext.html?is-external=true" title="class or interface in java.security"><code>AccessControlContext</code></a>. For example, a security | |
| policy provider that considers thread local values when evaluating security | |
| checks may want to include those values in snapshots of the current security | |
| context, so that they can be properly restored when the context is | |
| reapplied--it can achieve this by implementing the <code>getContext</code> | |
| method to return a <a href="../../../../net/jini/security/SecurityContext.html" title="interface in net.jini.security"><code>SecurityContext</code></a> instance containing the | |
| snapshotted thread local values as well as the current access control | |
| context, with <code>wrap</code> methods implemented to return privileged | |
| action wrappers that properly restore the thread local state.</div> | |
