This is is used as a companion to MessageTally. |
|
40 |
Instances of it are used to represent a calling chain. |
|
261 | 41 |
They are simply holders for some of the contexts values - no |
42 |
intelligence here. |
|
88 | 43 |
(MessageTally could have used the contexts themself, but these |
44 |
may create more overhead) |
