processing of jena rules

[Miguel Bento Alves]

A doubt about processing  of jena rules:

new triples generated by rules are saved in the model? or processed in
runtime, when the rule is invoked?

for instance, 
I have the following triples:
eg:A eg:p eg:B .
    eg:B eg:p eg:C .
    eg:C eg:p eg:D .
    
and the rule: 
[rule1: (?a <eg:p> ?b) (?b <eg:p> ?c) -> (?a <eg:p> ?c)]

The following triples are saved in the model or are generated every time the
rule is invoked?
eg:B eg:p eg:D .
eg:A eg:p eg:D .
eg:A eg:p eg:C .
