 In Thunder, interfaces are typically named with a capital `I` prefix, and the actual classes implementing these interfaces follow a consistent naming convention. The `IPlugin` interface can be a good example of that principle. This interface defines methods that any plugin must implement. Below you can see only a part of this interface and its methods with a detailed explanation. This code can be found [here](https://github.com/rdkcentral/Thunder/blob/e1b416eee5b057a8ffe5acfd68dfda04ad4f30eb/Source/plugins/IPlugin.h) in the Thunder repository.
