Classes
class	bm::Meter
class	bm::MeterArray

Detailed Description

Includes both the Meter and MeterArray classes. MeterArray is exposed in P4 v1.0.2 as the meter object. Action primitives can take a MeterArray reference as a parameter (but not a Meter though). Here is a possible implementation of the execute_meter() P4 primitive:

class execute_meter
  : public ActionPrimitive<MeterArray &, const Data &, Field &> {
  void operator ()(MeterArray &meter_array, const Data &idx, Field &dst) {
    dst.set(meter_array.execute_meter(get_packet(), idx.get_uint()));
  }
};
