may be a method like: #applyAssociation:fromSide:toSide:
or withFrom:withTo:
or fromRole:toRole:
...
from famix.
Currently to create an association such as Invocation, we must:
- in
#defineClasses
- create a class #Invoked-name
- create a class #Invoker-name
- create a class #Invok-name
- in
#defineHierarchy
- Invoked class uses
TInvocable
- Invoker class uses
TWithInvocations
- Invok class uses
TInvocation
- Invoked class uses
Things happen in two methods (#defineClasses
and #defineHierarchy
), often lines are separated because the classes have other properties/inheritances, so the information is scattered which does not make clear the creation of a relationship.
Improvement initially wished was to create classes as usual and define the relationship (i.e. uses of traits) in #defineRelations
:
apply: TInvocation on: Invok-class withFrom: Invoker-class withTo: Invoked-class
But we don't have identification of from/to slots in TInvocation
so we cannot compute the trait needed by the from/to sides.
from famix.
Two possible solutions:
- creating the classe in
#defineClasses
+ a method with 6 parameters:
applyAssociation: TInvocation on: Invok-class fromSlot: #sender on: Invoker-class toSlot: #candidates on: Invoked-class
(sender
is the from slot in TInvocation
and candidates
is the to slot)
- small variation: Invok class uses
TInvocation
(and no other!) in#defineHierarchy
:
applyAssociation: Invok-class fromSlot: #sender on: Invoker-class toSlot: #candidates on: Invoked-class
- Introduce a special notation for association creation so that the to and from slots are explicitly meta-described. There is already
FmxMBRelationSide>>source
andFmxMBRelationSide>>target
which could be some basis for this ...
