Nomenclature

[silkentrance]

This is about distinguishing parameterizable decorators from standard decorators from factory functions/methods that will return either of the two, since there has been quite a misunderstanding about standard decorators vs. parameterizable decorators and along that line also about decorator factories.

decorator

function decorator(...args)
{
   // decorate
}

parameterizable decorator

Note: it is not a factory

function decorator(parameters)
{
  return function decoratorImpl(...args)
  {
     // decorate
  };
}

decorator factory

is not a decorator, will produce instances of decorators

function factory(factoryOptions)
{
     // e.g.
     return function parameterizableDecorator(parameters)
     {
        //...
     };
}
