questions about Discrete2d objects

[Tamas Papp]

Hi,

A few questions about Discrete2d objects. Do they (meaning Discrete2d and
its subclasses) store the object and the value at the same spot? I mean,
one cannot put an object and a value at the same (x,y) coordinate, because
they overwrite each other. Is it this way? 

Is there a way to store objects in, for example, a Ca2d lattice, give them
a message that returns a value, and have that value displayed by
Object2dDisplay? I mean, not the objects displaying themselves, but
Object2dDisplay doing the job, as if they were values, not objects.

Thanks is advance,

Tamas
