public abstract class AllValuesOrNoneFieldMutatingUpdateProcessor
extends FieldMutatingUpdateProcessor

Abstract subclass of FieldMutatingUpdateProcessor for implementing UpdateProcessors that will mutate all individual values of a selected field independently. If not all individual values are acceptable - i.e., mutateValue(srcVal) returns SKIP_FIELD_VALUE_LIST_SINGLETON for at least one value - then none of the values are mutated: mutate(srcField) will return srcField.
