Sum(3pm) LogReport's Lire Documentation Sum(3pm)NAMELire::Sum - Lire class that implements the sum operatorSYNOPSISuse Lire::SumDESCRIPTIONClass that implements the sum operator. This operator will compute the field's sum in a group of DLF records. It's possible to compute a weighted sum in which each value is first multiplied by the value of another DLF field. Its also possible to express the count as a ratio of the total count for the group or table.METHODSnew( %params ) Creates a new Lire::Count object. In addition to the values supported by its parents, the weight and ratio attributes will be initialized to the values specified in the %params argument. weight( [$new_weight] ) Returns the DLF field's name by which the values will be multiplied before being summed. You can change the weight field by specifying a new name as the $new_weight parameter. Use undef to remove the use of a weighting field. ratio([$new_ratio]) Returns how the sum will be expressed. This can one of three possible values: none Default. The absolute sum will be used. group The sum will be expressed as a percentage of the group's sum. table The sum will be expressed as a percentage of the table's total sum.SEE ALSOzLire::ReportSpec(3pm), Lire::ReportOperator(3pm), Lire::Aggregator(3pm), Lire::Aggregate(3pm).AUTHORFrancis J.
