33 * This is an initializer for interfaces plugin. Its main goal is to revers-engineer configuration data (config "true")
34 * for interfaces model from operational data. In this case, we are trying to recreate Interfaces container from InterfacesState
35 * container. Thanks to symmetrical nature of the model, it's pretty straightforward.
37 * This is very useful when the lower layer already contains some data that should be revers-engineer to config data
38 * in honeycomb in order to get HC and lower layer to sync... It makes life of upper layers much easier
40 * However it's not always possible to perform this task so the initializers are optional for plugins
