Examples of gnu.java.security.action.SetAccessibleAction

gnu.java.security.action.SetAccessibleAction
PrivilegedAction implementation that calls setAccessible(true) on the AccessibleObject passed to its constructor. Example of use: Field dataField = cl.getDeclaredField("data"); AccessController.doPrivileged(new SetAccessibleAction(dataField));

                    if (mp[j] != params[j])
                    {
                        continue outer;
                    }
                }
                AccessController.doPrivileged(new SetAccessibleAction(m));
                return m;
            }
        }
    }
    return null;
