We would not require to make an explict call to any of the methods above as they are called by the Flex framework itself, we only need to plugin in the custom code in the invocation sequence appropriately. Refer to the link “More Info” for a comprehensive documentation of the usage of the methods.
We may not need to override all of them, but it is important to know the appropriate method to be overriden. Also do not forget to call the implementation of the base class unless you are really sure to do so.
