[Wonder-disc] Filters

[Martin S. <mar...@ae...>]

All,

not sure if filter is the right term here, but heres the question.

i have a number of objects to which i'm adding an 'installation' identifier
so that i can segregate data.

Theres already a large codebase accessing these objects.

What i want to do is, whenever i issue a query against those objects,
'filter' on installation, i.e., only select those objects which to refer to
a particular installation.

Obviously i could amend every fetch currently in place (which may take some
time!) but i wondered if there was something analogous to Springs idea of
aspects (sort of)?

i.e. can i 'trap' each query and filter to/limit to a particular value?

many thanks

martin
