Below are example implementations of the Duplicate Check Prevention Plugin, each demonstrating a different business use case.

Basic Example Code

global class DefaultPrevention implements dupcheck.dc3Plugin.InterfacePrevention {
    global void processStatus(Set<Id> recordIdSet, dc3Plugin.PreventionStatus status) {
      
        // YOUR CUSTOM CODE
        
        // Log basic metadata
        System.debug('Prevention Plugin executed with status: ' + status);
        System.debug('Record(s) being processed: ' + recordIdSet);
        
        // Additional custom logic can be added here based on the status.
        // For example, you could branch your logic as follows:
        /*
        if (status == dc3Plugin.PreventionStatus.DUPLICATE) {
            // Execute logic specific to duplicate detection.
        } else if (status == dc3Plugin.PreventionStatus.UNIQUE) {
            // Execute logic for unique records.
        }
        */
        
        return;
    }
}

Example 1: Record Reassignment Prevention Plugin

This example demonstrates a use case where, if the Prevention Plugin determines that a record's status is DUPLICATE, the record ownership is changed to a designated queue. This ensures that the record is not assigned to a sales representative, but instead is routed to a review queue for further processing.

global class RecordReassignmentPreventionPlugin implements dupcheck.dc3Plugin.InterfacePrevention {
    global void processStatus(Set<Id> recordIdSet, dc3Plugin.PreventionStatus status) {
        // Proceed only if the status is DUPLICATE
        if (status == dc3Plugin.PreventionStatus.DUPLICATE) {
            // Query the records (assumed to be Leads in this example)
            List<Lead> leadsToUpdate = [SELECT Id, OwnerId FROM Lead WHERE Id IN :recordIdSet];
            
            // Set the new owner ID to a specific queue
            Id queueId = '00GXXXXXXXXXXXX';
            
            // Update the owner of each Lead record to the queue
            for (Lead l : leadsToUpdate) {
                l.OwnerId = queueId;
            }
            
            try {
                update leadsToUpdate;
                System.debug('Records reassigned to queue for review: ' + recordIdSet);
            } catch (DmlException e) {
                System.debug(LoggingLevel.ERROR, 'Error reassigning records: ' + e.getMessage());
            }
        }
        return;
    }
}
