Question

when i look into api.joomla.org to view available functions i always see a Little GREEN Vertical Bar to all functions where they are explained, but some functions have orange bar what they mean by orange and green bars ? for batter understand i also included a snapshot below

1. i also read JModelList class file and i found a function getListQuery() but this function is not shown at Joomla JModelList api page, is this function going to be deprecated.?
2. secondly how do i view only function that are not inherited from base class!

Answer 1

Green marked functions are public ones. Orange are protected. Private methods are red.

1) Look at the filter buttons in the left hand side. Maybe some functions do not appear according to how these are set.

2) You have, as I said, filters above the left-handed list of functions. These you can use to filter out inherited methods (by clicking down the "Inherited"-Button).
