java - Injecting Collection of Classes with Guice -


i'm trying inject things google guice 2.0 , have following structure:

fooaction implements action baraction implements action

i have actionlibrary following constructor:

actionlibrary (list<action> theactions)

when request instance of actionlibrary guice, guice identify both of registered action classes (fooaction, baraction) , pass them constructor. motivation here being when add third action bazaction, simple registering in module , automatically added list in constructor.

is possible?

what want multibindings. specifically, want bind set<action> (not list, set want anyway) this:

multibinder<action> actionbinder = multibinder.newsetbinder(binder(), action.class); actionbinder.addbinding().to(fooaction.class); actionbinder.addbinding().to(baraction.class);

then can @inject set<action> anywhere.
