Lire::First3pm
Lire class that implements the first operator
Usage
use Lire::First
Overview
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.
Methods
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.
