I remember an optCoerceNilToNull, but that seems to 1) Only apply to pointer types (which could mean having to use char *, not String, and thus need to do encoding/decoding manually) 2) Be scoped to entire call, not single parameter (may or may not be more than a philosophical objection) Might be worth a shot though?

Ok, thanks Esteban. Do you plan to integrate it in Voyage or should we look into it? Any starting point? Never done something similar.

Hi, Voyage did not implement GridFS out of the box. But It can be extended to use it, it does not looks as a real complicated API.

MongoGB GridFS driver for Pharo

by roberto.minelli＠usi.ch

Hi guys, I need to store objects (i.e., mongo documents) which exceeds the BSON-document size of 16MB. I run into the âofficialâ mongoDB solution, which is to use GridFS. Does anyone know if there is any possibility to use GridFS within Pharo? For example with Voyageâ¦ or any other suggestion is highly appreciated! Cheers, Roberto

I know that there are week collections, but I what to have a âvariableâ that wonât prevent the object it points to be garbage collected. If a class is weak it is also variable. So you have basically two solutions. If your variable is an instance variable, you can declare that your class is weak and initialize it with a size of 1, the fixed fields will remain strong, only the indexed field will be weak. You can have a look at WeakKeyAssociation and WeakValueAssociation for examples. Otherwise, you can wrap your variable into a weak array of size 1. Later slots will be able to do the job transparently. > Uko
