• Method Summary

  All Methods

  Modifier and Type	Method and Description
  T	create (CreationalContext<T> creationalContext) Create a new instance of the contextual type.

• Method Detail

  • create

    T create(CreationalContext<T> creationalContext)

    Create a new instance of the contextual type. Instances should use the given CreationalContext when obtaining contextual references to inject, in order to ensure that any dependent objects are associated with the contextual instance that is being created. An implementation may call CreationalContext.push(Object) between instantiation and injection to help the container minimize the use of client proxy objects.

    Parameters:

    creationalContext - the context in which this instance is being created

    Returns:

    the contextual instance

    Throws:

    CreationException - if a checked exception occurs while creating the instance

  • destroy

    void destroy(T instance,
     CreationalContext<T> creationalContext)

    Destroy an instance of the contextual type. Implementations should call CreationalContext.release() to allow the container to destroy dependent objects of the contextual instance.

    Parameters:

    instance - the contextual instance to destroy

    creationalContext - the context in which this instance was created
