◆ GetDescription()

void AppleThreadPlanStepThroughDirectDispatch::GetDescription	(	Stream *	s,
		lldb::DescriptionLevel	level
	)

overridevirtual

Print a description of this thread to the stream s.

thread. Don't expect that the result of GetThread is valid in the description method. This might get called when the underlying Thread has not been reported, so we only know the TID and not the thread.

Parameters

[in]	s	The stream to which to print the description.
[in]	level	The level of description desired. Note that eDescriptionLevelBrief will be used in the stop message printed when the plan is complete.
