LineNumbers

object LineNumbers

This is a minimized byte-code parser that concentrates exclusively on line numbers and source file extraction. It works for all normal classes up to format 52:0 (JDK8), and it also works for Lambdas that are Serializable. The latter restriction is due to the fact that the proxy object generated by LambdaMetafactory otherwise contains no information about which method backs this particular lambda (and there might be multiple defined within a single class).

    Scala API: Obtain line number information for the class defining the given object.

    Scala API: Obtain line number information for the class defining the given object. This is done by reading the byte code (a potentially blocking IO operation) and interpreting the debug information that it may contain.

    This does not work for Java 8 lambdas that are not Serializable, because the language designers have consciously made it impossible to obtain the byte code for those.
