Parameter Passing

  • Throughout TM, the TMObjs.$makeparamrow() and TMObj.$loadparamvars() functions are used for passing parameters between objects. This method is favoured over passing individual parameters to a top-level class, especially when a large number of the parameters are optional. See wModeless.$construct for an example.
  • When over-riding any method:
    • always put the parameters in place that the superclass has:
      • in the same order (verify the order always)
      • document with the same parameter definitions
      • copy whatever documentation from the superclass and augment with why you are over-riding the class if it is not obvious
  • All parameters are to have an initial value specified for default case. 0, kTrue, Kfalse or #NULL is acceptable if no value is wanted
