Re: [rules-dev] Query on drools
Yes, it would be possible, Rules, after compilation, are available as
Abstract Syntax Trees, representing the conditions. However, to access
these objects, you need to use classes from the "unstable" part of the
API, and there won't be much documentation helping you along.
Let me say that this is a very roundabout way of defining limits for
data generation. A conidtion is nothing but a boolean expression with
extensions such as "forall", "exists", "not",
"collect", "accumulate",
which (I think) you won't be using anyway.
But I reserve my judgement because I don't know the specification for
your data generator.

Hi,
I'm not using drools to generate data, a java program would do that. I just
want to know whether the java program can connect to drools, fetch
corresponding rules from it and generate data based on the rule fetched(the
conditions for data generation and the upper and lower limits come from
rules). Please let me know if this is possible.

Praveen.
