A Discrete2d is basically a 2d array of ids. Subclasses add particular space semantics onto this. Currently Discrete2d grids are accessed by integer pairs of X and Y coordinates.
Example space/Discrete2d/1.
Discrete2d instances can now serialize themselves (without needing
additional classes such as Int2dFiler).
The result of value (shallow) Lisp serialization of a 4x3 Discrete2d
consisting of long values might be:
(list
(cons 'myDiscrete2d
(make-instance 'Discrete2d
#:xsize 4 #:ysize 3 #:lattice
(parse
#2((1000 1000 1000 1000)
(1000 1000 1000 1000)
(1000 1000 10 1000))))))
For object (deep) Lisp serialization of the same 4x3 lattice with
identical instances of MyClass at each point (except at (2,2) which
has an instance of MyClassOther) would look like:
(list
(cons 'myDiscrete2d
(make-instance 'Discrete2d
#:xsize 4 #:ysize 3 #:lattice
(parse
(cons '(0 . 0)
(make-instance 'MyClass #:strVal "Hello World"))
(cons '(0 . 1)
(make-instance 'MyClass #:strVal "Hello World"))
(cons '(0 . 2)
(make-instance 'MyClass #:strVal "Hello World"))
(cons '(1 . 0)
(make-instance 'MyClass #:strVal "Hello World"))
(cons '(1 . 1)
(make-instance 'MyClass #:strVal "Hello World"))
(cons '(1 . 2)
(make-instance 'MyClass #:strVal "Hello World"))
(cons '(2 . 0)
(make-instance 'MyClass #:strVal "Hello World"))
(cons '(2 . 1)
(make-instance 'MyClass #:strVal "Hello World"))
(cons '(2 . 2)
(make-instance 'MyClassOther #:strVal "Other World"))
(cons '(3 . 0)
(make-instance 'MyClass #:strVal "Hello World"))
(cons '(3 . 1)
(make-instance 'MyClass #:strVal "Hello World"))
(cons '(3 . 2)
(make-instance 'MyClass #:strVal "Hello World")))))) |
