Description

Pattern: begin("A", SkipToNext()).oneOrMore().allowCombinations().followedBy("C").notFollowedBy("B").within(Time.milliseconds(10L))

Sequence: <a1, 1L> <a2, 2L> <a3, 3L> <c1, 4L> will produce

[a1, a2, a3, c1]

[a1, a2, c1]

[a1, c1]

[a2, a3, c1]

[a2, c1]

[a3, c1]

Using SkipPastLastEvent() also produce the same result.
