# Module.class_variables (from ruby core) --- mod.class_variables(inherit=true) -> array --- Returns an array of the names of class variables in *mod*. This includes the names of class variables in any included modules, unless the *inherit* parameter is set to `false`. class One @@var1 = 1 end class Two < One @@var2 = 2 end One.class_variables #=> [:@@var1] Two.class_variables #=> [:@@var2, :@@var1] Two.class_variables(false) #=> [:@@var2]
