NAME
Lire::Timegroup - Base class for implementation of the timegroup aggregator SYNOPSIS
use Lire::Timegroup; DESCRIPTION
This module is the base class for implementation of the timegroup aggregator. This aggregator will split the DLF records based on a time period controlled throught the period attribute. For example, using 1d as the period value, this aggregator will group all records in the same day period together. CONSTRUCTOR
new( %params ) Creates a new instance of a timegroup aggregator. In addition to the normal report operator parameters, the timegroup aggregator can take several parameters: field This optional parameter contains the DLF field which contains the time value used to group the DLF records together. See the field() method for more information. period This mandatory parameter should contains the period's length that will be used to group the records. See the period() method for more information. METHODS
field( [$new_field] ) Returns the DLF field's name that is used to group the DLF records. This should be a valid timestamp DLF field in the current schema. By default, the default timestamp field of the DLF schema is used. You can change the field by passing a $new_field parameter. period( [$new_period]) Returns the period's length in which the records are grouped. This can either be a duration value or the name of a report specification's parameter containing a duration value. The period's length can be changed by using the $new_period parameter. SEE ALSO

NAME
Lire::First - Lire class that implements the first operator SYNOPSIS
use Lire::First DESCRIPTION
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.
