setDefaultTimeBase

void setDefaultTimeBase(TimeConverter* tc);

Sets the default time base for the link. This will be the units of send latency if additional latency is added using send() without specifying units.

note

Calls to registerClock() and registerTimeBase() can also affect a (sub)component's default time base.

Parameters​

  • tc (TimeConverter*) A TimeConverter representing the default units of latency to use on the link
  • returns none

Example​
