// FormatMessage and FormatErrorMessage
|

|

// This file defines two K2Nodes: FormatMessage, and FormatErrorMessage. The
|
|
// only difference between them is that the former outputs the message as an
|
|
// output pin. The latter outputs the message to the log instead.
|
|
//
|
|
// To implement code reuse, we put all the code into FormatMessage, and made
|
|
// FormatErrorMessage a derived class of FormatMessage. The derived class
|
|
// doesn't override anything - all it does is set a flag, the flag changes
|
|
// the behavior of FormatMessage.
