Field Detail

PROP_CHECK_PRIOR_LISTS_EMPTY

@S4Boolean(defaultValue=false)
public static final java.lang.String PROP_CHECK_PRIOR_LISTS_EMPTY

This property is used in the Iterator returned by the getNonEmittingListIterator() method. When the Iterator.next() method is called, this property determines whether the lists prior to that returned by next() are empty (they should be empty). If they are not empty, an Error will be thrown.
