Is there a way to check againts built-in types in google apps script?
I don't know how to access contructors of built-in types. So I can't use instaceof operator.

For example Profile (https://developers.google.com/apps-script/class_analytics_v3_schema_profile )

function getReportDataForProfile(profile) {

if (profile instanceof Profile) // Profile is undefined...

...

}

Also what is a litle confusing: When I get an instance of Profile (in variable profile)

profile.constructor // is undefined

It seems that this won't be a necessarily clean solution, but it will be functional nonetheless.

If it is a Profile object, then profile.getKind() will return analytics#profile. However, if the .getKind() method is not defined for that object, it will throw an error. So it looks like you'll have to do 2 checks.

if (typeof profile.getKind != function) {

  if (profile.getKind() == analytics#profile) {

    //profile is a Profile!

  } else {

    //profile is some other kind of object

    //use getKind() to find out what it is!

  }

} else {

  //profile doesn't have a getKind method

  //need a different way of determining what it is

}
