12.2. Pattern Example
This is what a pattern looks like:
rule "2 unconnected patterns"
when
Pattern1()
Pattern2()
then
... // actions
end
// The above rule is internally rewritten as:
rule "2 and connected patterns"
when
Pattern1()
and Pattern2()
then
... // actions
end
Note
An
and cannot have a leading declaration binding. This is because a declaration can only reference a single fact at a time, and when the and is satisfied it matches both facts.
