       Lire::First - Lire class that implements the first operator


       use Lire::First


       Class that implements the first operator. This operator will output the first value
       appearing in its field when the DLF records are sorted according to the "sort_fields"
       attribute. The default sort order is the default timestamp sort.


   new( %params )
       Creates a new Lire::First object. The field attribute can be specified in the "field"
       parameter and the sort order can be passed in the "sort_fields" parameter.

   sort_fields( [$new_sort_fields] )
       Returns the fields that are going to be used to sort the DLF records.  This a reference to
       an array of DLF field names.

       If the $new_sort_fields parameter is set, it will be used as the new sort order. It must
       be an array reference and should only contains valid field names for the current report
       specification's schema.

       When no sort_fields are set, the default is to use the default timestamp field.


        Lire::ReportSpec(3pm), Lire::ReportOperator(3pm),
        Lire::Aggregator(3pm), Lire::Aggregate(3pm), Lire::Last(3pm)
