      Description copied from class: `FilterIteration`
      Tests whether or not the specified object should be returned by this Iteration. All objects from the wrapped Iteration pass through this method in the same order as they are coming from the wrapped Iteration.
      Specified by:
        `accept` in class `FilterIteration<BindingSet,QueryEvaluationException>`
      Parameters:
        `bindings` - The object to be tested.
      Returns:
        `true` if the object should be returned, `false` otherwise.
