Wrap(ICollector[])

Wraps a list of ICollectors with a MultiCollector. This method works as follows:

  • Filters out the null collectors, so they are not used during search time.
  • If the input contains 1 real collector (i.e. non-null ), it is returned.
  • Otherwise the method returns a MultiCollector which wraps the non-
    null
    ones.
