## Interface Configuration<T>

- All Known Implementing Classes:
    `ValidatingConfigurationWrapper`

      public interface Configuration<T>

  Object passed into a service contributor method that allows the method provide contributed values to the service's configuration. A service can collect contributions in three different ways:
  - As an un-ordered collection of values
  - As an ordered list of values (where each value has a unique id, pre-requisites and post-requisites)
  - As a map of keys and values
  This implementation is used for un-ordered configuration data. The service defines the type of contribution, in terms of a base class or service interface. Contributions must be compatible with the type.

    All Methods Instance Methods Abstract Methods
    Modifier and Type | Method | Description
    --- | --- | ---
    `void` | `add​(T object)` | Adds an object to the service's contribution.
    `void` | `addInstance​(java.lang.Class<? extends T> clazz)` | Automatically instantiates an instance of the class, with dependencies injected, and adds it to the configuration.

- - ### Method Detail

    - #### add

          void add​(T object)

      Adds an object to the service's contribution.
      Parameters:
        `object` - to add to the service's configuration

    - #### addInstance

          void addInstance​(java.lang.Class<? extends T> clazz)

      Automatically instantiates an instance of the class, with dependencies injected, and adds it to the configuration. When the configuration type is an interface and the class to be contributed is a local file, then a reloadable proxy for the class will be created and contributed.
      Parameters:
        `clazz` - what class to instantiate
