Class AsExtensions

  • public class AsExtensions
extends java.lang.Object
    An extension to be used with Lombok in order to provide "as" support to classes that don't implement the As interface. The typical usage is to retrofit legacy code. FIXME: this class doesn't cache - every as*() call instantiates new objects.
