Interface Lambda

All Known Implementing Classes:

InputLiteralLambda, InputProcessingLambda, ResourceBundleLambda, SpecCompliantLambda

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface Lambda

Lambda represents a special type of data - a callable object.

By default, a lambda is spec compliant. I.e. the input type is Lambda.InputType.LITERAL and isReturnValueInterpolated() returns true.
