* Register an assisted injection factory.
|

|
|
* <p>This function provides an automatic way to define a factory that creates a concrete type
|
|
* through assisted injection. For example to configure the following assisted injection case:
|
|
*
|
|
* <pre>
|
|
* public class Foo {
|
|
* public interface Factory {
|
|
* Foo create(int a);
|
|
* }
|
|
* @Inject
|
|
* Foo(Logger log, @Assisted int a) {...}
|
|
* }
|
|
* </pre>
|
|
*
|
|
* Just pass {@code Foo.Factory.class} to this method. The factory will be generated to return its
|
|
* one return type as declared in the creation method.
|
|
*
|
|
* @param factory interface which specifies the bean factory method.
