public class SequenceMatcher<T>
extends ListMatcher<T>

A matcher that will match if all the given matchers each match against an item that the previous matcher matched against. That means the second matcher should match an item that follow the item that the first matcher matched.

If the number of items is larger than the number of matchers, the excess items are not evaluated. Use Matchers.exactSequenceOf(org.hamcrest.Matcher[]) to match the sequence exactly. If the last item of the list has been evaluated, and Matchers still remain, they are evaluated against a null value.
