Tiered Subline Change Line Subline Updater Class

When a tiered pricing line is updated, added, or removed, this Apex hook can update that tiered pricing subline, other tiered pricing sublines on that parent line, parameter sublines on the same parent line, or the parent line.

The hook occurs when a user changes a field on a tiered pricing subline in the Edit Lines modal.

Apex hook class

• It must implement the zpl.TieredSublineChangeLineSublineUpdater interface.
• It must have a global access modifier.
• You must specify the Apex hook class name in the Tiered Subline Change Updater Class Name field of the Product Selector Configuration that is mapped to the Edit Lines Modal component to be affected by the hook.

Interface definition

global interface TieredSublineChangeLineSublineUpdater
{
    LinesAndSublinesResponse updateLineSublinesOnTieredSublineChange(LinesAndSublinesInputData data);
}


global class LinesAndSublinesInputData {
    @AuraEnabled global SObject changedSObject { get; private set; }
    @AuraEnabled global SObject line { get; private set; }
    @AuraEnabled global String changedFieldName { get; private set; }
    @AuraEnabled global List<SObject> parameterSublines { get; private set; }
    @AuraEnabled global List<SObject> tieredSublines { get; private set; }
    @AuraEnabled global Boolean isTieredSublineAdded { get; private set; }
    @AuraEnabled global Boolean isTieredSublineDeleted { get; private set; }
    @AuraEnabled global Boolean isTieredSublinesAllDeleted { get; private set; }

    global LinesAndSublinesInputData(SObject changedSObject, String changedFieldName, SObject line, 
                                        List<SObject> parameterSublines, List<SObject> tieredSublines,
                                        Boolean isTieredSublineAdded, Boolean isTieredSublineDeleted, 
                                        Boolean isTieredSublinesAllDeleted) {
        this.changedSObject = changedSObject;
        this.line = line;
        this.changedFieldName = changedFieldName;
        this.parameterSublines = parameterSublines;
        this.tieredSublines = tieredSublines;
        this.isTieredSublineAdded = isTieredSublineAdded;
        this.isTieredSublineDeleted = isTieredSublineDeleted;
        this.isTieredSublinesAllDeleted = isTieredSublinesAllDeleted;
    }
}

Example: LinesAndSublinesResponse response

global class LinesAndSublinesResponse {
    @AuraEnabled global SObject line;
    @AuraEnabled global List<SObject> parameterSublines;
    @AuraEnabled global List<SObject> tieredSublines;

    global LinesAndSublinesResponse(SObject line, List<SObject> parameterSublines, List<SObject> tieredSublines)
    {
        this.line = line;
        this.parameterSublines = parameterSublines;
        this.tieredSublines = tieredSublines;
    }
}
