One more question about fame/famix entities and fuel exporter - Moose-dev

30 May 2012

Hi guys.  Right now, our extension to export Moose models does the
following:

accepts: anObject
    MooseModel meta
        descriptionOf: anObject class
        ifAbsent: [ ^ false ].
    ^ true

so....if an object is NOT found in the #descriptionOf:  then we use the
normal Fuel serialization. If it WAS found, then we do something like:

FLFameCluster >> referencesOf: anObject do: aBlock

    self attributes
        do: [ :anAttribute |
            | values |
            values := anAttribute getFrom: anObject.
            (self shouldIgnore: anAttribute withAll: values)
                ifTrue: [ aBlock value: 0 ]
                ifFalse: [
                    aBlock value: values size.
                    values do: [ :aValue | aBlock value: aValue ] ] ]

and

shouldIgnore: attribute withAll: values
    "Copied from FMRepositoryVisitor>>ignoreProperty:withAll:"

    ^ values isEmpty or: [
        attribute isDerived or: [
            attribute type == FM3MetaDescription boolean and: [
                values size == 1 and: [
                    values first == false ]]]]

so...basically we follow all attributes.

Now...my question is (actually, Martin), instead of doing the "if" to see
whether I should do that or the normal fuel procedure, instead of being
MooseModel meta      descriptionOf: anObject class      ifAbsent:
can be:   "object kindOf: MooseEntity" ?

would that be the same?   in other words, all what is included in
descriptionOf: are MooseEntities?  all MooseEntities (whether they are
included in descriptionOf: or not should be ne serialized that way?

I ask because it would make the code much easier.

thanks
