RE: [picocontainer-dev] comments on injection

My other (main) use case is injection... 

When I have

@Inject

private MyClass _myClass;

 

If MyClass is not registered then it gets registered automatically in
Pico. With this feature, I hardly have any "initialization" code in my
projects. I just start my project by creating a container and everything
else gets wired automatically. I'm not sure how this could work out with
"getInstance".

 

Erik.

What other usecase is there Erik ?

 

For the one you;ve given :-

 

+          @Test

+          public void testDynamicRegistration() {

+                      MutablePicoContainer pico = new
DefaultPicoContainer();

+                      ComponentLocator dynamicReg = new
DynamicRegistrationLocator();

+                      pico.addLocator(dynamicReg);

+                      LinkedList<String> list =
pico.getComponent(LinkedList.class);

+                      assertNotNull(list);

+          }

 

 

I might prefer ..

 

+          @Test

+          public void testDynamicRegistration() {

+                      MutablePicoContainer pico = new
DefaultPicoContainer();

+                      LinkedList<String> list =
pico.addComponent(LinkedList.class).getInstance();  // getInstance() is
new and implicitly on the last component added ~  v easy to implement

+                      assertNotNull(list);

+          }

 

I know you have a 'bigger' use of your way up your sleeve :-)
