[rules-users] bytecode representation of rules

[Edson Tirelli]

   Tough question to answer as not everything in a DRL file becomes
bytecode, and not all in the same place. For instance, rule consequences
and other semantic code blocks, when using the java dialect, will become a
class that is code generated and compiled in memory. You can see that code
by setting the dump dir option in the KnowledgeBuilderConfiguration object
(or -Ddrools.dump.dir=<path> on the command line).

   Constraints on the other hand will become a mix of JIT bytecode and/or
MVEL expressions and/or object accessors, depending on several factors.
Since they are shared among multiple rules, they don't belong to a single
rule in particular, but become part of the Rete network, that is basically
an in-memory data structure.

   Not exactly sure if this helps you...
