◆ getPort()

Port & MemCheckerMonitor::getPort	(	const std::string &	if_name,
		PortID	idx = `InvalidPortID`
	)

overridevirtual

Get a port with a given name and index.

This is used at binding time and returns a reference to a protocol-agnostic port.

Parameters

if_name	Port name
idx	Index in the case of a VectorPort

Returns: A reference to the given port

void MemCheckerMonitor::init ( )

overridevirtual

init() is called after all C++ SimObjects have been created and all ports are connected.

Initializations that are independent of unserialization but rely on a fully instantiated and connected SimObject graph should be done here.
