Emily,
Yes, this is not supported since generics information is not available at
runtime, and in this way, we can't constrain facts by generics information.

2007/7/6, Emily Harsh <[EMAIL PROTECTED]>:
Hello,
I'm using Drools 4.0M3. Several of the objects in our object model take
advantage of generics. I was able to utilize generics in the consequences
by setting the Java language level to 1.5 in the
PackageBuilderConfiguration, however I would also like to optimize my rule
activations by using the concrete types in the conditions. I'm assuming
this is not currently supported since I get the following error when I try
to specify the concrete type in the condition:
mismatched token: [EMAIL PROTECTED],1242:1242='<',<78>,30:15]; expecting type
LEFT_PAREN[30,45]
My working rule uses the following syntax:
rule "Test Generics"
when
Span () # 4.0: Can we use concrete type Span<Integer>?
then
System.out.println("RULE: Matched Span()");
end
I would like to be able to specify the concrete type like this:
rule "Test Generics 2"
when
Span<Integer> ()
then
System.out.println("RULE: Matched Span<Integer>()");
end
Our object model uses the generic type "Span" heavily. I am hoping that I
will be able to reduce the number of rule activations by specifying the
concrete type in the condition.
Any chance this will be available in the 4.0 general release?
Thanks!
Emily
