• JavaClass allows to implement business rules using a call to an external java class
• JavaClass can be used to compute any field in the quote header, any column and total cell of the quote spreadsheet
• On column/total cell computation rules: Java class cannot be used to update (via the API) the quote spreadsheet data
• JavaClass can be used to define the domain of values of any field in the quote header, any column and total cell of the quote spreadsheet

The association with the JavaClass is made through the full path of the java class (package + class), therefore each java class must have a unique name within a given quote model.

A standard JavaClass ExtractInformationGrid deployed in the

package com.accesscommerce.cart.runtime.computations allows to retrieve, in a spreadsheet column mapped with an extension field of type BINARY, the content of a Sales Information Grid (SIG) attached to a sales breakdown line which is object to the creation of a quote line or subline.

The table below details the service parameters:

List of values

The Java class must implement the "AbstractJavaComputation" interface which has a public method: String[][] getLVA(ModelCompilation modelC,String lvaName,String languageId,CartController controller Tuple[] parameters)

</**

* Returns a LVA.

* LVA is:

* ID1=VALUE1_FR or VALUE1_US

* ID2=VALUE2_FR or VALUE2_US

* @param modelC The model compilation

* @param lvaName The LVA name

* @param languageId The language id

* @param controller The cart controller

* @param parameters The array of parameters

* @return String[][] with codes and values

* @throws CartException

Computation with dependencies

Computation without dependence The Java class must implement the "AbstractJavaComputation" interface which has a public method: execute
