-/* connectWith() :
- - modify all necessary attributes in the model to create a connection
- between current InterfaceItem and iface. Note that the source and destination
- are deduced from the direction (In, Out) and the type of the owner (funcitonal, group)
-
- CAUTION: No security checks are done. This method must be called only if canConnectWith has been called and returned true.
-
- NOTE : conditions so that this InterfaceItem can be connected with inter.
- (i.e. current one can connect to inter OR inter can connect to current)
-
- Here are all the possible combinations, depending on the type of the
- block/item and direction of the interface, which are :
- GI/GB : a GroupItem referencing a GroupBlock (single solution for GI)
- BI/FB : a BlockItem referencing a FunctionalBlock
- BI/GB : a BlockItem referencing a GroupBlock
-
- For GI/GB:
- - Input can connect with BI/FB or BI/GB Input
- - Output can connect with BI/FB or BI/GB Output
-
- For BI/FB:
- - Input can connect with:
- GI/GB Input
- BI/FB Output
- BI/GB Output
- - Output can connect with:
- GI/GB Output
- BI/FB Input
- BI/GB Input
-
- For BI/GB:
- - Input can connect with:
- GI/GB Input
- BI/FB Output
- BI/GB Output
- - Output can connect with:
- GI/GB Output
- BI/FB Input
- BI/GB Input
-
- And whatever the case an InOut can only connect with an InOut
- We note that:
- - the IG does not allow the connect a GI/GB interface to an
- interface of another GI/GB, thus the case is not considered above.
- - BI/FB and BI/GB are the same.
- - the cases where direction are the same only occur when
- the 2 items are of different type (GI and BI)
- - the cases where directions are different only occur when
- the 2 are of both BlockItem
