AUTOLOAD
Each entry in either %FUNCS or %GLOBALS is used by AUTOLOAD() to create
dynamic methods.
Each entry in either %FUNCS, %GLOBALS, or MIB Leaf node names present in
loaded MIBs are used by AUTOLOAD() to create dynamic methods.
Note that this AUTOLOAD is going to be run for all the classes listed in
the @ISA array in a subclass, so will be called with a variety of
package names. We check the %FUNCS and %GLOBALS of the package that is
doing the calling at this given instant.
1. Returns unless method is listed in %FUNCS or %GLOBALS for given class
2. If the method exists in %GLOBALS it runs $info->_global(method)
unless already cached.
3. Method is in %FUNCS
4. Run $info->_load_attr(method) if not cached
5. Return $info->_show_attr(method).
1. Returns unless method is listed in %FUNCS, %GLOBALS, or is MIB Leaf
node name in a loaded MIB for given class.
2. Checks for load_ prefix and if present runs $info->_global(method)
for methods which exist in %GLOBALS or are a single instance MIB Leaf
node name, otherwise runs $info->_load_attr(method) for methods which
exist in %FUNCS or are MIB Leaf node name contained within a table. This
always forces reloading and does not use cached data.
3. Check for set_ prefix and if present runs $info->_set(method).
4. If the method exists in %GLOBALS or is a single instance MIB Leaf
node name it runs $info->_global(method) unless already cached.
5. If the method exists in %FUNCS or is MIB Leaf node name contained
within a table it runs $info->_load_attr(method) if not cached.
6. Otherwise return $info->_show_attr(method).
Override any dynamic method listed in one of these hashes by creating a
subroutine with the same name.
