An array of channel sets that comprise this log. A log must have at least one channel set, and may have more than one. The channel set is evaluated in such a way that the channels in the log is a UNION of all of the channels in the array of channel sets. That is to say, the result is also a set, no channel can appear more than once in a given log. |
