Extend list constructor SQL/OQL queries to allow conditions on associated objects #11

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Currently, you can express conditions on the unary primitive-type attribute 
values of the data type being fetched into a list. (Technically, also primitive 
attributes of supertypes of the data type too.)

It would be very useful to allow the expression of join queries to filter the 
result list based on conditions on attributes of associated/related objects, 
and maybe even indirectly related objects in the object relation/component 
network.

Probably, dot-notation should be used (similar to OQL I think) to refer to the 
joined objects e.g.

cars = Car[] "engine.timingBelt.model.name = 'ACME 1305-B'

Fixed to allow one level like engine.horsepower > 100

May want to extend to at most a few more levels eventually.
