Ways of Controlling Anger

What are some techniques that the Lord Buddha have stated to control anger? I can recall a few (listed below) but I not really sure if they are exactly correct. - changing the object of your attention - thinking about the consequences of your anger - understanding what is the cause of your anger - metta loving kindness meditation towards yourself - channelling your anger towards your own mind and trying to control your own mind Could someone please verify if the Lord Buddha actually stated the above techniques and also could you please state any other techniques He stated. It would also be great if you could reference the suttra. Thank you in advance.
