Class SecureAction
java.lang.Object
org.apache.felix.framework.util.SecureAction
public class SecureAction
- extends Object
This is a utility class to centralize all action that should be performed
in a doPrivileged() block. To perform a secure action, simply
create an instance of this class and use the specific method to perform
the desired action. When an instance is created, this class will capture
the security context and will then use that context when checking for
permission to perform the action. Instances of this class should not be
passed around since they may grant the receiver a capability to perform
privileged actions.
