abstract class Delambdafy extends SubComponent with Transform with TypingTransformers with TreeDSL with TypeAdaptingTransformer
This transformer is responsible for preparing Function nodes for runtime, by translating to a tree that will be converted to an invokedynamic by the backend.
The main assumption it makes is that a Function {args => body} has been turned into {args => liftedBody()} where lifted body is a top level method that implements the body of the function. Currently Uncurry is responsible for that transformation.
From this shape of Function, Delambdafy will create:
An application of the captured arguments to a fictional symbol representing the lambda factory.
This will be translated by the backed into an invokedynamic using a bootstrap method in JDK8's LambdaMetaFactory
.
The captured arguments include this
if liftedBody
is unable to be made STATIC.
