Class ListUtils

  • public class ListUtils
extends Object
    Utilities for dealing with CAS List types. The many places operations-to-set-values are done to update feature values, which use the notIndexed form, because list elements cannot be part of an index key. Creation methods don't journal, these are guaranteed to be above the line.
