Hi,
I had a look on that.
The problem is that in the method #primCollectAtScope, when the #collectAsSet finds a classScope = nil (for example, in a GlobaVariable) it inserts a SetElement and not nil.
primCollectAtScope: aScopeSymbol
"
^ self opposites collectAtScope: aScopeSymbol
"
^self storage collectAsSet: [ :dep | (self opposite: dep) perform: aScopeSymbol ].
See the difference:
#(nil) collectAsSet: #yourself.
#(nil) collect: #yourself.
So, if you check the method #collectAtScope: there is a filter for nil elements, but we will never have nil (just SetElement).
One trivial solution is:
primCollectAtScope: aScopeSymbol
"
^ self opposites collectAtScope: aScopeSymbol
"
^ (self storage collect: [ :dep | (self opposite: dep) perform: aScopeSymbol ]) asSet
I just commited it and the tests are green for FamixPropertiesTest.testHasTheSamePropertiesAs
ps: also updated the invocation from #queryAllOutgoingDependencies to #queryAllOutgoingAssociations Doru cited last email.--On Tue, Jan 31, 2012 at 8:43 PM, Tudor Girba <tudor@tudorgirba.com> wrote:
Hi Nicolas,
Thanks a lot.
I looked quickly into this. There is at least a simple problem: you are calling queryAllOutgoingDependencies, but this method does not exist anymore. I guess we should replace this with queryAllOutgoingAssociations.
Is this due to a wrongly published refactoring?
Cheers,
Doru
