10.8. Declaring a New Fact Type Example

In this example, a new fact type called Address is used. This fact type will have three attributes: number, streetName and city. Each attribute has a type that can be any valid Java type, including any other class created by the user or other fact types previously declared:

declare Address
   number : int
   streetName : String
   city : String
end

declare Address
   number : int
   streetName : String
   city : String
end
