Method Details

execute

public DeleteOutput execute(DeleteInput deleteInput)
                     throws QException

Throws:

QException

performValidations

public List<QRecord> performValidations(DeleteInput deleteInput,
 Optional<List<QRecord>> oldRecordList,
 boolean isPreview)
                                 throws QException

this method takes in the deleteInput, and the list of old records that matched the pkeys in that input. it'll check if any of those pkeys aren't found (in a sub-method) - a record with an error message will be added to oldRecordList for any such records. it'll also then call the pre-customizer, if there is one - taking in the oldRecordList. it can add other errors or warnings to records. The return value here is basically oldRecordList - possibly with some new entries for the pkey-not-founds, and possibly w/ errors and warnings from the customizer.

Throws:

QException
