public class AssertGroupSizeLessThan
extends AssertGroupBase

Class AssertGroupSizeEquals is an GroupAssertion that asserts the number of items in the current group is less than the given size.

If a patternString is given, only grouping keys that match the regular expression will have this assertion applied. Note multiple key values will be delimited by a tab character.
