<!-- Internal events are only to be used during development, i.e. temporary time measurements, without the need
to modify .jfc files etc. Code that commits an internal event should NEVER be checked in.
Example usage:
#include "jfr/jfrEvents.hpp"
void foo() {
EventDuration event;
bar();
baz();
event.commit();
}
$ make images
$ java -XX:StartFlightRecording:settings=none,filename=dump.jfr ...
...
$ jfr print dump.jfr
Programmatic access:
try (var rf = new RecordingFile(Path.of("dump.jfr)) {
while (rf.hasMoreEvents()) {
RecordedEvent e = rf.readEvent();
System.out.println(e.getName() + " " + e.getDuration()));
