What is Guice ?
What were the reasons to start with Guice ?
You're almost expanding injection to static typing ?
Guice is the first injection framework to leverage 1.5 features ?
Where is Guice being used ?
Can you generate byte code ?
What are the next features for Guice ?
Can Guice let developers generate classed on the fly ?
It would be nice if we had the same (injection) framework from SE to EE.
You also worked on the Google Collections API, can you tell a bit more ?
What are the differences between weak and soft references ?
Which are the interesting soft, weak, strong (reference) combitions in practice ?
What are the future features for Google collections ?
Anything else you want to talk about ?
Put simply, Guice alleviates the need for factories and the use of new in your Java code. Think of Guice's @Inject as the new new. You will still need to write factories in some cases, but your code will not depend directly on them. Your code will be easier to change, unit test and reuse in other contexts.
Guice embraces Java's type safe nature, especially when it comes to features introduced in Java 5 such as generics and annotations. You might think of Guice as filling in missing features for core Java. Ideally, the language itself would provide most of the same features, but until such a language comes along, we have Guice.
Guice helps you design better APIs, and the Guice API itself sets a good example. Guice is not a kitchen sink. We justify each feature with at least three use cases. When in doubt, we leave it out. We build general functionality which enables you to extend Guice rather than adding every feature to the core framework.
Guice aims to make development and debugging easier and faster, not harder and slower. In that vein, Guice steers clear of surprises and magic. You should be able to understand code with or without tools, though tools can make things even easier. When errors do occur, Guice goes the extra mile to generate helpful messages.
