.public abstract TriggerSequence[] getPrefixes()
Returns a list of prefixes for the current sequence. A prefix is any
leading subsequence in a TriggerSequence
. A prefix is
also an instance of TriggerSequence
.
For example, consider a trigger sequence that consists of four triggers: A, B, C and D. The prefixes would be "", "A", "A B", and "A B C". The list of prefixes must always be the same as the size of the trigger list.
