How to use scala to test variable of Type Map?

Question

The following code has the warning value.isInstanceOf[Map[Any,Any]]

non-variable type argument Any in type Map[Any,Any] is unchecked since it is eliminated by erasure

How to eliminate the warning while still able to check data of the Type Map[Any,Any]?

Thx :）

`Any` is symptom the type safety is not ok there – cchantep Sep 01 '17 at 05:59 — cchantep, Sep 01 '17 at 05:59

This will work:

value.isInstanceOf[Map[_, _]]

Additional approaches are described in the answers to this question.
