This means that you've declared a local variable which has the same name as
an instance variable (either of that class or one of its super classes).
GCC allows this, but what happens is that you cannot get access to the
instance variable within the scope of that local variable; that is what the
warning means when it says "hides".  The easy fix is to rename the local
variable to something else like 'anAgentList'
