Re: Can I Inject x Class?

2018-06-21 Thread Joe DeSantis 
The method that was used prior was: injector.getExistingBinding(key)).
isPresent()
It did accurately identify all explicit bindings, however it did not work 
with just-in-time bindings.

Re: Can I Inject x Class?

Jukito takes another approach. They use an ElementVisitor to collect all 
bindings and then decide if the required binding is in the module(s).

Have a look at the BindingsCollector.java class

So my question is simply, what is the best way of determining if you 
can get an instance of a particular class given an injector.

Can I Inject x Class?

2018-06-20 Thread Joe DeSantis 
I was working with a JUnit 5 extension for Guice, and we had the need to 
determine if a particular class was able to be injected by an injector.
The only solution we came up with is attempting to get an instance with 
that Injector. (Literally calling the getInstance method, in a try/catch 
block).
So my question is simply, what is the best way of determining if you can 
get an instance of a particular class given an injector.
