| | protected Condition | getAssignmentCondition(String id, AST condition, AST action, HashMap<String, Entity> symbolTable)
generates the conditions for an assignment on the left hand side example:
(defrule wholesalerPricing ?x <- (SKU (wholesalerOnly true) (sellPrice
?price)) => (modify ?x (sellPrice 0) (listPrice (* ?price 0.75)
(discountPrice (* 0.5 ?price))))
needs to be: (defrule wholesalerPricing (?id clazz SKU) //
getConditionTemplate returns from here (?id wholesalerOnly true) (?id
sellPrice ?price) // to here (?id listPrice ?id_var_1) (?id discountPrice
?id_var_2) => (retract (?id listPrice ?id_var_1)) (retract (?id
discountPrice ?id_var_2)) (retract (?id sellPrice ?price)) (assert (?id
sellPrice 0)) (assert (?id listPrice (* ?price 0.75))) (assert (?id
discountPrice (* ?price 0.5))))
for achieving that, we first iterate over the actions to select the
attributes that will be modified on the selected object. | | protected LinkedList<AttributeValuePair> | getAttributesThatModifyActionsUseFromVariable(String id, String variable, AST action)

| getAssignmentCondition | | protected Condition getAssignmentCondition(String id, AST condition, AST action, HashMap<String, Entity> symbolTable)(Code) | | generates the conditions for an assignment on the left hand side example:
(defrule wholesalerPricing ?x <- (SKU (wholesalerOnly true) (sellPrice
?price)) => (modify ?x (sellPrice 0) (listPrice (* ?price 0.75)
(discountPrice (* 0.5 ?price))))

discountPrice ?id_var_2)) (retract (?id sellPrice ?price)) (assert (?id
sellPrice 0)) (assert (?id listPrice (* ?price 0.75))) (assert (?id
discountPrice (* ?price 0.5))))
for achieving that, we first iterate over the actions to select the
attributes that will be modified on the selected object. From those
actions we get the variables. In the above example that would include
listPrice and discountPrice. This operation is done in
getAttributesThatModifyActionsUseFromVariable After that, we modify the
attributes that are already in use in the conditions. Then we add the
attributes that were left as another condition to the condition list. and
finally creating the entity for the symbol table to be use when
generating the actions

| getAttributesThatModifyActionsUseFromVariable | | protected LinkedList<AttributeValuePair> getAttributesThatModifyActionsUseFromVariable(String id, String variable, AST action)(Code) | | this method returns the that the modify actions modify
on the specified variables the values are generated dynamically based on
the id

| replaceAttributesThatAreInConditions | | protected void replaceAttributesThatAreInConditions(LinkedList<AttributeValuePair> attributesList, Condition condition)(Code) | | We check each condition to make sure that the conditions that were
already in the rule are not define twice
