- - ### Method Detail

    - #### public void registerBinding(Class<U> type, Class<? extends U> implementationType)

      Registers a binding from the specified "public" domain object type to the specified implementation type. Whenever the container is asked to create an element with the binding's public type, it will instantiate the binding's implementation type. If the implementation type has a constructor annotated with javax.inject.Inject, its arguments will be injected.

      In general, registering a binding is preferable over implementing and registering a factory.

      Parameters:
        `type` - a public domain object type
        `implementationType` - the corresponding implementation type
        `` - a public domain object type

    - #### public void registerFactory(Class<U> type, NamedDomainObjectFactory<? extends U> factory)

      Registers a factory for creating elements of the specified type. Typically, the specified type is an interface type.

      throws:
        IllegalArgumentException if the specified type is not a subtype of the container element type
      Parameters:
        `type` - the type of objects created by the factory
        `factory` - the factory to register
        `` - the type of objects created by the factory

    - #### public void registerFactory(Class<U> type, groovy.lang.Closure<? extends U> factory)

      Registers a factory for creating elements of the specified type. Typically, the specified type is an interface type.

      throws:
        IllegalArgumentException if the specified type is not a subtype of the container element type
      Parameters:
        `type` - the type of objects created by the factory
        `factory` - the factory to register
        `` - the type of objects created by the factory
