I've just managed to get incremental compilation working, was actually
quite a small change. This means that you set a RuleBase on a
PackageBuilder and it'll update the RuleBase ass you add drls to it - it
avoids the creation and merging of a temporary Package, which was needed
for shell environments.
I've also updated drools-clips to support deftemplates via the
ClassBuilder, so it generates internal pojos underneath. I've updated
the unit test to show this working, as the class is internal to Drools I
had to use reflection to instantiate the facts :)
I'll commit this tomorrow, once I've improved it further.
public void testTemplateCreation() throws Exception {
this.shell.eval( "(deftemplate Person (slot name (type String) )
(slot age (type int) ) )" );
this.shell.eval( "(defrule yyy => (printout t yy \" \" (eq 1 1)
) ) )" );
this.shell.eval( "(defrule xxx (Person (name ?name&bob) (age 30)
) (Person (name ?name) (age 35)) => (printout t xx \" \" (eq 1 1) ) )" );
WorkingMemory wm = shell.getStatefulSession();
Class personClass =
this.shell.getStatefulSession().getRuleBase().getPackage( "MAIN"
).getPackageScopeClassLoader().loadClass( "MAIN.Person" );
Method nameMethod = personClass.getMethod( "setName", new
Class[] { String.class } );
Method ageMethod = personClass.getMethod( "setAge", new Class[]
{ int.class } );
Object bob1 = personClass.newInstance();
nameMethod.invoke( bob1, "bob" );
ageMethod.invoke( bob1, 30 );
wm.insert( bob1 );
Object bob2 = personClass.newInstance();
nameMethod.invoke( bob2, "bob" );
ageMethod.invoke( bob2, 35 );
wm.insert( bob2 );
wm.fireAllRules();
assertEquals( "yy truexx true",
new String( this.baos.toByteArray() ) );
}
