This class represents one of two things:

Arguments in a call to a service

Use the attributes of this class as arguments to methods. You shouldn't make instances of this class. Each attribute should be used as a named argument in the calls that expect this type of object.

As an example, if Att1 is expected to be a Paws::EMR::ScalingRule object:

$service_obj->Method(Att1 => { Action => $value, ..., Trigger => $value  });

Results returned from an API call

Use accessors for each attribute. If Att1 is expected to be an Paws::EMR::ScalingRule object:

$result = $service_obj->Method(...);
$result->Att1->Action
