XF 1.5 Custom BB Code php callback class & function definition

[v8td]

Hi!

Where i can define the new class and function for PHP Callback?

Please explain me this help line:
"This callback will receive these parameters: array $tag, array $rendererStates, XenForo_BbCode_Formatter_Base $formatter."

- $tag = is the tag of the custom bb code? ... So i can define a generic "handler" class, and function where i use if..else if like: ... if($tag == "myPhoto"){//php code}... else if($tag == "myTable"){//php code}) ?

I must echo the $result, or just use return $result from function?

- what is $redererStates and $formatter?

- how to pass parameters? As json?
- can i define as many params as i need?

Some example for a more complicated custom bb code?

I hope i posted this question in right place.
