Member Function Documentation

◆ CalculateStopInfo()

bool ThreadPostMortemTrace::CalculateStopInfo ( )

overrideprotectedvirtual

Ask the thread subclass to set its stop info.

Thread subclasses should call Thread::SetStopInfo(...) with the reason the thread stopped.

A thread that is sitting at a breakpoint site, but has not yet executed the breakpoint instruction, should have a breakpoint-hit StopInfo set. When execution is resumed, any thread sitting at a breakpoint site will instruction-step over the breakpoint instruction silently, and we will never record this breakpoint as being hit, updating the hit count, possibly executing breakpoint commands or conditions.

Returns: True if Thread::SetStopInfo(...) was called, false otherwise.
