This is is used as a companion to MessageTally.
|
|
|
41 |
Instances of it are used to represent a calling chain.
|
|
261
|
42 |
They are simply holders for some of the contexts values - no
|
|
|
43 |
intelligence here.
|
|
88
|
44 |
(MessageTally could have used the contexts themself, but these
|
|
|
45 |
may create more overhead)
