class ConfigVariableList

Bases: ConfigVariableBase

This class is similar to ConfigVariable, but it reports its value as a list of strings. In this special case, all of the declarations of the variable are returned as the elements of this list, in order.

Note that this is different from a normal ConfigVariableString, which just returns its topmost value, which can optionally be treated as a number of discrete words by dividing it at the spaces.

A ConfigVariableList cannot be modified locally.
