Detailed Description

PortWrapper Object Declaration.

The RequestPortWrapper and ResponsePortWrapper converts inherit-based RequestPort and ResponsePort into callback-based. This help reducing redundant code and increase code reusability in most cases, allowing composition over inheritance pattern.

Example usage:

class MySimObject : public SimObject { public: ResponsePortWrapper inPort;

MySimObject(...) : inPort("in_port", this)... { inPort.setGetAddrRangesCallback([this]() { return getRange(); });

inPort.setAtomicCallbacks([this](PacketPtr packet) { // process the packet ... return Tick(); }); }

private: AddrRangeList getRange() const {...} };
