Suppose I have an interface like this:
@FunctionalInterface
public interface ModifierFunction {
Game applyModifier(Game game, Card card, Modifier modifier);
}
and some class where I use it:
SHOWDOWN_BUFF((game, card, modifier) -> {
game. // <- I get no proposals from Eclipse here
return game;
})
My problem is that if I press Ctrl+Space I can't see Game's methods...in fact I get no proposals at all. It does not work if I use this syntax either:
SHOWDOWN_BUFF((Game game, Card card, Modifier modifier) -> {
game. // <- I get no proposals from Eclipse here either
return game;
})
How can I get code completion to work in Eclipse Luna for Java 8?
edit: I'm using Version: Luna Service Release 1 (4.4.1)

Passing Lambda Expressions as ArgumentsIf you pass an integer as an argument to a function, you must have an int or Integer parameter. If you are passing an instance of a class as a parameter, you must specify the class name or the object class as a parameter to hold the object.
Q 5 - Which of the following is correct about Java 8 lambda expression? A - Lambda expressions are used primarily to define inline implementation of a functional interface.
Type Inference means that the data type of any expression (e.g. method return type or parameter type) can be deduced automatically by the compiler. Groovy language is a good example of programming languages supporting Type Inference. Similarly, Java 8 Lambda expressions also support Type inference.
Lambda Expressions were added in Java 8. A lambda expression is a short block of code which takes in parameters and returns a value. Lambda expressions are similar to methods, but they do not need a name and they can be implemented right in the body of a method.
Parameter completion within Java 8 Lambda expression works with Eclipse Mars (4.5.0). https://www.eclipse.org/eclipse/news/4.5/jdt.php
