[binarycloud-dev] Module Communication - Total Confusion

[Justin F. <je...@ey...>]

Alex:

Sometimes my mind just falls apart, and I feel like I am in that
state right now.  In one of your last posts, you suggested to
get a large/complex bit of data and store it in a class variable,
and then (implied) down the load chain, this variable can
be accessed.

HOW?

Especially, what if I want something from a module in a group
when they are two instances, but do different things because
of passed in options.

EXAMPLE stanza / module group top
    'modules' => array(             
            'top' => array(         
                    'load'  => array(
                            array(
                                    'name'          => "EyeLibrary",
                                    'package'       => "lib",
                                    'load_order'    => "1",
                                    'options'       => "option1",
                            ),
                            array(  
                                    'name'          => "EyeLibrary",
                                    'package'       => "lib",
                                    'load_order'    => "2",
                                    'options'       => "option2",
                            ),
                            array(          
                                    'name'          => "Blank",
                                    'package'       => "lib",
                                    'load_order'    => "3"
                            ),      
                    ),              
            ),                      
----------
Now in the above stanza, EyeLibrary that has load order "1"
does something as dictated
by option1, and stores that data at, say, $this->what_i_need.

EyeLibrary that has load order "2" does something as dictated
by option2, and stores that data at, say, $this->what_i_need.

NOW, how the hell do I get the data EyeLibrary[0]->what_i_need?
NOW, how the hell do I get the data EyeLibrary[1]->what_i_need?
Both of these pieces of data are desired in Blank, load order
"3".

If I instantiate a new EyeLibrary within a following module,
this is no good at all, because I have in the constructor
something like:

        function EyeLibrary($_options="ain't no options in EyeLibrary")
{
                $this->options  = $_options;
		some other code, maybe
                return true;
        }

so all I would get was "ain't no options...", which, for the example,
is EyeLibrary->what_i_need.

How do I do this without going global????

You instantiate the thing in $Page->_IncludeModules() with the
options from $bc_page, but how do I get to that instantiation, and
distinguish
between the two loads????  WITHOUT GOING GLOBAL SCOPE
in the constructor???

My mind is mush right now...
