man Lire::Last () - Lire::Last
NAME
Lire::Last
SYNOPSIS
FIXME
DESCRIPTION
Class that implements the first operator. This operator will output the last value appearing in its field when the DLF records are sorted according to the CWsort_fields attribute. The default sort order is the default timestamp sort.
METHODS
Creates a new Lire::Last object.
sort_fields( [$new_sort_fields] )
Returns the fields that are going to be used to sort the DLF records. This a reference to an array of DLF field names.
If the CW$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. =cut
