Lire::Count \- Lire class that implements the count operator
.SH "SYNOPSIS"

.Vb 1
\& use Lire::Count
.Ve
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
Class that implements the count operator. This operator counts the
number of \s-1DLF\s0 records in the current group.
.PP
If the fields attribute is set, the count statistics will be equals to
the number of different values present in the fields specified by that
attribute.
.PP
Its also possible to express the count as a ratio of the total count
for the group or table.
.SH "METHODS"
.IX Header "METHODS"
.ie n .SS "new( %params )"
.el .SS "new( \f(CW%params\fP )"
.IX Subsection "new( %params )"
Creates a new Lire::Count object. In addition to the values
supported by its parents, the fields and ratio attributes will be
initialized to the values specified in the \f(CW%params\fR argument.
.SS "fields( [$new_fields] )"
.IX Subsection "fields( [$new_fields] )"
Returns the fields for which we are counting the different values.
This a reference to an array of \s-1DLF\s0 field names.
.PP
If the \f(CW$new_fields\fR parameter is set, it will be used as the new
\&\f(CW$fields\fR value. It must be an array reference and should only contains
valid field names for the current report specification's schema.
.SS "ratio([$new_ratio])"
.IX Subsection "ratio([$new_ratio])"
Returns how the count will be expressed. This can one of three
possible values:
.IP "none" 4
.IX Item "none"
Default. The absolute count will be used.
.IP "group" 4
.IX Item "group"
The count will be expressed as a percentage of the group's count.
.IP "table" 4
.IX Item "table"
The count will be expressed as a percentage of the table's total
count.
