Is there an API reference or documentation for Magento that I can refer to find out the methods available in the different Mage classes?
Let's say I want to find out more about the method
getBeforeAuthUrl(). Other than digging into the actual implementation, is there a documentation where I can find out where this method is available, what are its parameters, what does its boolean argument do, etc? How can I find out what other methods I can use in a certain Mage class?
I've been searching everywhere but I can't find one. I'm not sure if I'm missing out something, but digging into the Magento code just to find out what methods I can use and how I can use those methods is quite a pain for a beginner to learn, especially when Magento is massive.
