THanks Eliot for the explanation. So....The compiler checks and for these kind of special quick methods it creates a CompiledMethod that has in its header, a primitive value ? So...if I would be able to put a "self halt" (but I cannot do it becaue otherwise it won't be quick anymore) in Number>>isNumber, the debugger would never stop there? Interesting! Thanks Oscar for the question, it make me learn. Mariano 2010/10/22 Eliot Miranda <eliot.miranda@gmail.com>
Hi Oscar,
see Object class>>whatIsAPrimitive. Further, most of the primitive methods you're seeing are methods that answer self, nil, true false or an inst var. See the difference between these:
SystemNavigation new browseAllSelect: [:m| m isQuick]
SystemNavigation new browseAllSelect: [:m| m primitive > 0 and: [m isQuick not]]
SystemNavigation new browseAllSelect: [:m| m primitive > 0 and: [m isQuick not and: [(#(117 120) includes: m primitive) not]]]

Hi all,
I have a (basic) question:
What is a primitive method?
In pharo 1.1.1, we have CompiledMethod>>primitive that basically return:
0 if the method is not a primitive method
0 otherwise
But if you execute this on i.e. Number>>isNumber or Morph>>#model compiled methods you get that these two are primitive methods. Are they primitive methods?
Other (related) question is: When I executed the expression:
SystemNavigation default allPrimitiveMethods
, I get a OrderedCollection with 5581 elements. Are all those methods, primitive methods?
