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.
