Detailed Description

Store and load simulation attribute configuration.

ns-3 Objects and their attribute values (default, and per-instance values) are stored in a specialized internal database. The config-store module permits these values to be imported and exported to formats of different types (e.g. XML files, raw text files, or a GTK-based UI).

While it is possible to generate a sample config file and lightly edit it to change a couple of values, there are cases where this process will not work because the same value on the same object can appear multiple times in the same automatically-generated configuration file under different configuration paths.

As such, the best way to use this class is to use it to generate an initial configuration file, extract from that configuration file only the strictly necessary elements, and move these minimal elements to a new configuration file which can then safely be edited. Another option is to use the ns3::GtkConfigStore class which will allow you to edit the parameters and will generate configuration files where all the instances of the same parameter are changed.
