Lire::Timegroup(3) Base class for implementation of the timegroup aggregator


use Lire::Timegroup;


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.


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:
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.
This mandatory parameter should contains the period's length that will be used to group the records. See the period() method for more information.


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.
