PIDParameter

• This class represents the "PID" parameter

• According to the RFC, its value is either a single small positive integer or a pair of small positive integers separated by a dot. Multiple values may be encoded in a single PID parameter by separating the values with a comma ","

• Therefore, PIDParameter should be called with a single argument that is either:

  1. an instance of IntegerType

     If you intend the value to be a single small positive integer

     const pid = new PIDParameter(new IntegerType(3));
     
     // calling repr
     pid.repr();
     // PID=3

  2. an array of instances of IntegerType

     If you intend to have multiple values encoded in the parameter and separated by a comma

     const pid = new PIDParameter([new IntegerType(3), new IntegerType(7)]);
     
     // calling repr
     pid.repr();
     // PID=3,7

  3. a nested array of instances of IntegerType

     If you intend to have the value be a pair of small positive integers separated by a dot

     const pid = new PIDParameter([[new IntegerType(1), new IntegerType(5)]]);
     
     // calling repr
     pid.repr();
     // PID=1.5

• You may also combine the last two, as below

  const pid = new PIDParameter([
    [new IntegerType(1), new IntegerType(7)],
    new IntegerType(23),
    new IntegerType(24),
  ]);
  
  // calling repr
  pid.repr();
  // PID=1.7,23,24
