public class VATCalculationRuleCombineCmdImpl
extends CalculationCmdImpl
implements VATCalculationRuleCombineCmd

The default implementation of VATCalculationRuleCombineCmd.

This command only handle the sales tax and shipping tax when VAT(Value-Added-Tax) feature is enabled.

Its behaviour is as follows:

1. retrieves the calculation rules of the calculation code.
2. for each calculation rule:
   1. for sales/shipping tax only, ignore this calculation rule if it doesn't belong to the tax categories specified.
   2. if the calculation rule is restricted, invokes the calculation method of type "CalculationRuleQualify" referenced by the calculation rule (see CALRULE.CALMETHOD_ID_QFY, CalculationRuleQualifyCmd) to determine the list of qualified items.
   3. Calculate the rules and return the tax information using callRuleCalculate method. Original "CalculationRuleCalculate" is not used any more.
3. selects the combination of calculation rules (see CALRULE.COMBINATION) that yields the smallest total value.

Commands used:

• CalculationRuleQualifyCmd
Access beans used:
• CalculationMethodAccessBean
• CalculationCodeAccessBean
• CalculationRuleAccessBean
