I am having a little problem with the xTend syntax.|
I would like to pass a function to a utility-method, which applies this function to the filter of a list.
private def void doStuff(Iterable<MyType> list, (MyType) => Boolean filterFunction)
val result = list.filter[filterFunction] // syntax-error: cannot convert from (MyType) => (MyType) => Boolean to Function1
.... work on result
doStuff(intputList)[e | e.isTrue] // compiles nicely
My filterFunction maps MyType to Boolean, so why cant I use it in InterableExtensions.filter?
