3.2. Artop
Figure 3.8.: Version-specific generation of AUTOSAR API code from the respective AU-
TOSAR metamodels.
This situation requires the tool developer to implement the same tool functionality separately
for each AUTOSAR version. Consider an example where Artop should offer a function on a
QueuedReceiverComSpec model element 2 from figure 3.7 that requires reading the value of
its Queue Length property. The code will look like illustrated in listing 3.1:
( element autosar21 . swcomponent . communication .
QueuedReceiverComSpec ) {
queuedReceiver_21 = ( autosar21 . swcomponent . communication .
QueuedReceiverComSpec ) element ;
qrValue = queuedReceiver_21 . getQueueLength ();
...
} ( element autosar3x . swcomponent .
communication . QueuedReceiverComSpec ) {
queuedReceiver_3x = ( autosar3x . swcomponent . communication .
QueuedReceiverComSpec ) element ;
qrValue = queuedReceiver_3x . getQueueLength ();
...
} ( element autosar40 . swcomponent .
communication . QueuedReceiverComSpec ) {
2 The semantics of this element is irrelevant here, but can be found in the appropriate AUTOSAR template.
