Comment #4 on issue 3224 by luc.fabresse: Migrating MethodReference to
MethodReferenceWithSource
http://code.google.com/p/pharo/issues/detail?id=3224
some comments.
We must add a hash method on SourcedMethodReference.
I propose:
SourcedMethodReference>>hash
"Answer a SmallInteger whose value is related to the receiver's
identity."
^ super hash bitXor: self sourcePointer
All instances of SourcedMethodReference should (*must*) have a defined
sourcePointer (not be nil) at instanciation time.
But it seems that it is not the case since some initializing methods from
MethodReference are not redefined in SourcedMethodReference:
MethodReference>>setClass:methodSymbol:
MethodReference>>setClassAndSelectorIn:
MethodReference>>setClassSymbol:classIsMeta:methodSymbol:stringVersion:
MethodReference>>setClass:methodSymbol:stringVersion:
For example, in SystemNavigation a lot of methods use:
SourcedMethodReference new setClass: class methodSymbol: sel
which leave sourcePointer uninitialized.
Did these changes break some tests?
