Passing dynmic parameters to a third party library constructor

[Joseph]

Hello,

I need to make multiple objects of a client that takes a config object as a parameter. So for example, to do this using "new" I would do:

Config conf = new Conf(123, 444, "whatever");


Client client = new Client(conf);

I realize I can have a Provides method for Config and a Provides method for Client, that has Config injected, however, Config's parameters are not constant and not passed in the command line or a config file. They are constantly changing and from a db, and the row in the db is not constant, as I am making multiple objects. Config and Client are from third party libraries so I cannot add @Assisted to their constructors.

At some point you want to consider that wrapping db-reads in a Provider method is hiding too much logic in an abstraction. Stay thin if you can.

What would you gain with the injection?

Hi Freb,

I would prefer not to read from the db in a Provider method. I am trying to figure out how to inject an object that needs another object, that needs dynamic parameters so that I can avoid using "new".


Thanks,
Joseph
