This class performs compilation into ByteCodes. |
42 |
First, parsing is done using superclass methods, |
|
43 |
then the parse-tree is converted into an array of symbolic codes |
|
44 |
and a relocation table; |
|
45 |
these two are finally combined into a byteArray of the codes. |
|
0 | 46 |
|
19 | 47 |
(the intermediate step through symbolic codes is for debugging |
48 |
only - it will vanish) |
|
49 |
||
50 |
There are many dependencies to the run-time-system (especially the |
|
51 |
interpreter) in here - be careful when playing around ... |
