A question about lambda expressions without any sugar

[Sven L]

Hi!

i would like to see a lamba expression without any syntactic sugar. I wrote the following piece of code:

val (Person, Person)=>int le = ([ Person a, Person b |
    // ...
])

Collections::sort(collection, le)

1. What is the type that is automatically infered for the variable le? Can I replace "(Person, Person)=>int" with something else? Something with org.eclipse.xtext.xbase.lib.Functions.... or org.eclipse.xtext.xbase.lib.Procedures.... ?

Its not like that I want to write my lambda expressions this way. I'm just curious. ;-)

Best
Sven

It's Functions.Function2<? super Person, ? super Person, ? extends Integer>

You can check yourself by looking at the generated code (use the generated source view).
