[gme-users] BON interpreter problem about references - ConnectionEnd handling

[Zoltan Molnar]

Hi,

Once you have a connection c, you can inquire for its ends

ConnectionEnd ce = c->getSrc();

Or if you have a connected end src:

std::multiset<ConnectionEnd> cends = src->getConnEnds();

The handle has the magic of figuring out what is connected actually, a
referenceport or a modelport.

for( std::multiset<BON::ConnectionEnd>::const_iterator iter =
srcEnds.begin(); iter != srcEnds.end(); ++iter) {
	handle( *iter);
}

void handle( ConnectionEnd& p_connectionend)
{
	BON::FCO connend_fco( p_connectionend);
	if( connend_fco)
	{
		// the connected object is an fco ! 
	}
	else
	{
		BON::ReferencePort connend_refport( p_connectionend);
		if( connend_refport)
		{
			// it's a referenceport: see ReferencePortImpl
for details
			BON::FCO fco = connend_refport->getFCO();
			BON::ReferencePortContainer rpc =
connend_refport->getContainer();
			BON::Reference ref = rpc->getReference();
		}
		else ASSERT(0); // it can't happen
	}
}
