If all those slots contain references to 0 then they're still referring to a single object. The number of instances of SmallInteger is SmallInteger maxVal - SmallInteger minVal + 1, period. But they're virtual objects so they don't take any space; only their references take space. (IMO) So you could implement SmallInteger class>>instanceCount ^self maxVal - self minVal + 1 SmallInteger class>>allInstances ^self minVal to: self maxVal you could implement the following but it's of academic interest only; it'll take a long time on a 64-bit implementation ;) If you add this then you have to guard against it being invoked because shure as s**t someone will wonder why the system isn't doing anything when they ask some apparently reasonable question about instance counts...

by Schwab,Wilhelm K

Mariano, I see your point, but given the immediate object encoding tricks I'm not sure it's possible. Would the class methods #minVal and #maxVal be of any use to you?

I am not aware that any of the other existing PHP implementations has picked up Traits so far. PHP has no standard; the implementation is the standard, and Traits are being added to the implementation, hence, "standardization." My point remains; other languages are or have already adopted Traits while the Smalltalk community, from which the concept sprang, continues to drag its heels after nearly a decade since their introduction. >And well, it is about 3 years from the first implementation to a first release in an official alpha version of PHP. There is still a loooong way to go... No, there isn't, at least not compared with the rate of Smalltalk's adoption of Traits. Face it. There are just too many Smalltalkers who seem to think the language is a complete revelation that no mortal has the right to amend. Other languages can grow to accommodate new features; Smalltalk, which went through a number major revisions in the 70s at PARC, remains frozen in the amber of 1980. >Best regards >Stefan > > >-- >Stefan Marr >Software Languages Lab >Vrije Universiteit Brussel >Pleinlaan 2 / B-1050 Brussels / Belgium >http://soft.vub.ac.be/~smarr >Phone: +32 2 629 2974 >Fax: +32 2 629 3525 > > >

[Pharo-project] is there an easy way to know the SmallInteger instances?

by Mariano Martinez Peck

If I do SmallInteger alIInstances I get an empty array, and of course, with SmallInteger instanceCount I get zero. Now, I can understand that from the VM point of view, but for the final user, this should be polymorphic. For example, for instanceCount, I would like to know all the "variable slots" that has a 1 in the last bit. Is this already possible? if true, which message? if not, should I hack in the vm and code a primitive that does this? And the same for allInstances, if I can inspect 5, I should be also to inspect SmallInteger allInstances, and SmallInteger allInstances first, etc.... thanks Mariano
