Forgot the rule that creates the output :-)
rule isConnected
when
$r1: Room()
$r2: Room( this != $r1 )
$d: Door( fromRoom == $r1, toRoom == $r2 )
then
System.out.println( $d + " connects " + $r1 + " and " + $r1 );
end

Works as you'd exprect it - and here we go:
declare Thing
size : int

// A room is also a thing
declare Room extends Thing
name : String @key

// A door is a pathway between two rooms
declare Door extends Thing
fromRoom : Room @key
toRoom : Room @key

rule "startup"

There are no fancy hidden things in this bean generator, so your Door
would have an empty constructor and a constructor with two Room parameters:
Door door = new Door( fromRoom, toRoom );

But what if you now have 2 declare statements in which one defines itself
in terms of the other ...
// A room is also a thing
declare Room extends Thing
name : String @key
end
One would instantiate an object like this:
Room room = new Room("office");
// A door is a pathway between two rooms
Awesome! Thank you! :-)

Drools bytecode generates these beans without generating java source
code (if you are using the declare, not the data modeller). Having said
that, it is very simple:
declare Here
location: String @key
end
Generates a java class roughly equivalent to:
public class Here implements Serial
In recent versions, knowledge bases allow to retrieve "fact types" by
package and class name.
Those may be the descriptor classes that you are looking for

I was looking for something along the lines of a method of inspecting the
resulting code of any arbitrary @key declarations I might want to deploy. Is
there such a way?

The declare results in a bean, with constructors according to what you
have written, with getters and setters, and methods overriding toText,
equals and hashCode.

Is there any way to interrogate exactly, as in get a printed representation
of what goes on under the hood for one of these type of declarations ?
As an example: (as per the docs) for a declared type like the following:
declare Person
*firstName : String @key*
*lastName : String @key*
10 matches
