Why does all scala sections get obtained from ScalaObject
, although this feature is completely empty And there is no view in it?) Compared to AnyRef
, which defines additional methods?
This method will not be as slow as a call like equals ()
or hash code ()
because it should take into consideration the second class (which Ways to override)?
Is it possible to multiply AnyRef and ScalaObject in a class?
Update: With ScalaObject Scala's new version 2.10.
scalabject
a $ tag
method , In which, according to the comment, "Pattern matching is necessary to adapt expressions that match the builders of the case classes." Since the name starts with $
, the program programmer should be considered as "hidden". In Scala 2.8, it is completely empty, so I think it is for backward compatibility.
