Class of objects that are capable of handling interrupts.
All objects to be assigned in Plugbox must be derived from this class.
Each inheriting class must now define the virtual method Gate::epilogue(). For the virtual method Gate::epilogue() an empty implementation can be specified in this parent class, so derived device classes do not necessarily have to define an Gate::epilogue() on their own.
- Note
- To be able to enqueue each class inheriting from Gate into the linked list(s) implemented by GateQueue this class has to contain a member acting as
next pointer (for MPStuBS, each of the Core::MAX CPU cores will need its own pointer)
◆ ~Gate()
Destructor.
Classes with virtual methods should always have a virtual destructor (which can be empty as well). In StuBS this will calm the compiler, on other systems this will guarantee that delete will free the memory for objects of the derived classes correctly.
◆ prologue()

pure virtual |
Device-specific interrupt handling routine that is executed immediately after the interrupt occurs (asynchronously).
- Returns
true if the epilogue has to be executed.
Implemented in Assassin, WakeUp, Keyboard, Panic, and Watch.
◆ epilogue()
| virtual void Gate::epilogue |

inlinevirtual |
Possibly delayed, synchronously executed Device-specific interrupt handling routine.
Reimplemented in Assassin, Keyboard, and Watch.
