Examples of DynamicPolicyProvider

net.jini.security.policy.DynamicPolicyProvider
Security policy provider that supports dynamic granting of permissions at run-time. This provider is designed as a wrapper to layer dynamic grant functionality on top of an underlying policy provider. If the underlying provider does not implement the {@link DynamicPolicy} interface, then itspermission mappings are assumed to change only when its {@link Policy#refresh refresh} method is called. Permissions are granted on thegranularity of class loader; granting a permission requires (of the calling context) {@link GrantPermission} for that permission. @author Sun Microsystems, Inc. @since 2.0
