Re: [rules-dev] use of declared facts
Look at this unit test for some examples:
http://anonsvn.jboss.org/repos/labs/labs/jbossrules/trunk/drools-compiler...
// Retrieve the generated fact type
FactType cheeseFact = ruleBase.getFactType(
"org.drools.generatedbeans.Cheese" );
// Create a new Fact instance
Object cheese = cheeseFact.newInstance();
// Set a field value using the more verbose method chain...
// should we add short cuts?
// cheeseFact.getField( "type" ).getFieldAccessor().setValue(
cheese,
//
"stilton" );
cheeseFact.set( cheese,
"type",
"stilton" );
assertEquals( "stilton",
cheeseFact.get( cheese,
"type" ) );

There's now possibility to declare facts in the drl, like:
declare Person
name: String
age: int
end
My question is how do I instantiate this fact object during runtime? Do I
still need to have class Person compiled and existing somewhere in
classpath, or there's a helper class which I can use "fake the fact",
something like:
FakeFact person = FakeFact("Person");
person.setField("name", "Oleg");
person.setField("age", "42");
session.insert(person);
Or there's another nicer way?
Thank you,
