@ApiImplicitParam for Map objects

Question

I have a API which accepts One string, and One MAP as the input.

public ModelClass getMyApi(String inparm, Map<String, String> myValues)

I am wondering how can i capture MAP input in swagger document using @ApiImplicitParams, @ApiImplicitParam annotations.

I have tried with like this

 @ApiImplicitParam(name="myValues", value="Validation Values Map", required =
         true, dataType = "Map", paramType = "query")

But no luck.

Note: Am using Swagger-servlet Module.

Thanks.
