[Moose-dev] Re: Some FAMIX questions

Currently, quite a lot of space seem to be taken up by not-filled instvars. In my Delphi based Whitestar model, 406085 out of 664371 are either nil or empty sets. In a JHotDraw model from inFusion it is 724408 out of 1351527 Stephan FAMeasurements>measure varSize := mClass instSize. instSize := mClass allInstances size. nrNil := 0. nrEmpty := 0. mClass allInstancesDo: [ :instance | 1 to: varSize do: [:varIndex | |value| value := instance instVarAt: varIndex. value ifNil: [ nrNil := nrNil+1 ]. value isCollection ifTrue: [ value ifEmpty: [ nrEmpty := nrEmpty+1 ] ] ] ] MeasureFAMIX>initializeMeasurements FAMIXEntity withAllSubclassesDo: [ :each | self measurements add: (FAMeasurements new mClass: each; yourself). ] MeasureFAMIX>run self initializeMeasurements. measurements do: [ :each | each measure] MeasureFAMIX>sum nrOfVars := 0. nrEmpty := 0. measurements do: [ :measurement | nrOfVars := nrOfVars + (measurement varSize * measurement instSize). nrEmpty := nrEmpty + measurement nrEmpty + measurement nrNil].
