Everyone deals with their anger in different ways and everyone has a different 'structure' to what promotes and fans their rage. There are certain commonalities that all of us will recognise about anger but it is important to recognise that we are all as much individuals in our 'flaws' as we are our 'virtues'.
In my case, for example, I was born with what you might term a very 'direct' method of inter-personal negotiations i.e. disagreements usually ended in a fight. That took a lot of years for my dad to knock out of me but by the time I reached secondary school age, he'd succeeded. He succeeded so well that I have ever since been known for my calm, unrufflable demeanour (up until my bike accident at any rate).
The anger was still there tho', I just had a heavy chain holding back the release of that anger. Even today it is easy to tell if I have been enraged in an argument - I simply shut up and avert my gaze from the person in question so that they don't see the, to me, shameful emotion in my eyes. If my hands are shaking slighty then I've really lost my temper, I just haven't let it out.
Even post-bike-accident, I still have that part of my anger in my control but sadly these days there is sometimes something of a verbal outburst before I manage to screw the lid on tight enough

.
Inanimate objects, I'm ashamed to say, sometimes do not fare so well. I still generally have enough sense not to 'lay about' something fragile when it has fired my ire but there have been a couple of occasions which are both embarassing and retrospectively humerous to recall

. Fortunately none of my demeaning tantrums have had witnesses to either themselves or their aftermath.
Control of your temper is a very positive attribute and one that is never to be undervalued
but it is sadly the case that nearly all of us will lose our temper publicly at one time or another. As others have posted above, what matters then is how you handle the aftermath of the event and how you map out what you can do to avoid the same 'trigger' in the future.
