The total time spent in {@link ParserATNSimulator#adaptivePredict} for
this decision, in nanoseconds.
<p>
The value of this field contains the sum of differential results obtained
by {@link System#nanoTime()}, and is not adjusted to compensate for JIT
and/or garbage collection overhead. For best accuracy, use a modern JVM
implementation that provides precise results from
{@link System#nanoTime()}, and perform profiling in a separate process
which is warmed up by parsing the input prior to profiling. If desired,
call {@link ATNSimulator#clearDFA} to reset the DFA cache to its initial
state before starting the profiling measurement pass.</p>
