## Interface Convention

- All Superinterfaces:
    `ExtensionContainer`

      public interface Convention
      extends ExtensionContainer

  A `Convention` manages a set of convention objects. When you add a convention object to a `Convention`, and the properties and methods of the convention object become available as properties and methods of the object which the convention is associated to. A convention object is simply a POJO or POGO. Usually, a `Convention` is used by plugins to extend a `Project` or a `Task`.
