Visibility between layers and handlers and objects?

Dear OpenMappers--

I am trying to update some location (OMGraphic) objects on a map. The setup
is as follows:

1. I invoke OpenMap, which uses the properties file to create a
LocationLayer and a Handler for our objects
2. I then instantiate our OMGraphic objects in classes outside of the
LocationLayer and Handlers.
3. I then want to get access to the Layer so that we can add our objects to
the associated OMGraphicList -- a member of our LocationLayer

Item 3 is what I cannot figure out. I know that I can go from the Handler
to the Layer using the getLayer() method, but I don't know how to access the
Handler (since the properties file and Open Map take care of that behind the
scenes).

Due to design reasons, I would prefer NOT to instantiate the OMGraphic
objects inside the Handler.

I guess, the bottom line is that I want to get to the OMGraphicsList object
inside my LocationLayer from ANY object....

Thank you for your help (again :) )
