I don't understand why I should use a query! I already have an instance of the object fetched from the repo but its attributes are not resolved when read from an iterator block: I can't pick up the one I want. These attributes are not root, to the contrary to what I wrote initially.

Please commit/fix GAMysqlBinReader>>#timeStampFrom:

by Holger Freyther

Hi, on Pharo5 and "latest"(?) stable release of Garage it is implemented as: timeStampFrom: aStream "ByteStream" | dt | dt := self dateTimeFrom: aStream. ^ dt ifNil: [nil] ifNotNil: [dt asTimeStamp] There is no implementor of asTimeStamp. From what I read is a TimeStamp is a reduced range and asTimeStamp can be omitted? thank you holger

Hi, could you describe why you need this ? Do you have a usecase ? Just interested to know, as i work on similar mechanisms. Steven. Le 2017-03-03 14:55, Pablo R.

adding messages dinamically to a single instance object

Hi all. I need to know how can i do if i want add new behaviour ( a new method ) to a single instance object of a class.

Re: [Pharo-users] Voyage and instances retrieving

by Hilaire

Hi Esteban, I could, but I don't understand why the attribute does not resolve to an object equals to the other one in memory. If I add an inspect to the attributes, it resolves correctly and code work as expected: myObjectInRepo select: [ :each | each anAttribute inspect. someObjects includes: each anAttribute "the one Voyage should fetch"] There is some lazyness in resolving the object. I implemented = to bypass the == and primivite but it does not help. For efficiency and special aspect of the model, I prefer to stick to the Smalltalk iterators when possible.
