DESCRIPTION
This module offers an API to the subreports included in the sections of a Lire's report.

This object has all the methods that the Lire::Report::Group(3pm) object offers. You'll find more information on to access the data contained in a subreport in that man page.

CONSTRUCTORS

  new( $superservice, $type)
Creates a new Lire::Report::Subreport object. The $superservice parameter and $type parameters defines the report specification which was used to generate this subreport's data.

  new_missing( $superservice, $type, [$reason])
Creates a new Lire::Report::Subreport object marked as missing. The $superservice parameter and $type parameters defines the report specification which was used to generate this subreport's data. The $reason parameter sets the reason why this subreport is missing.

OBJECT METHODS

  id( [ $new_id ] )
Returns (and optionnally change) the id of this subreport. The subreport's ID uniquely identify it in its Report. Subreports with the same ID will be merged together.

  is_missing()
Returns true if this subreport was marked as missing in the XML file. A missing subreport is a subreport which was present in the report configure file but which was marked as missing in the XML report. This happens when the report specification requires fields that weren't available in the DLF files generated. It can also happen when an error occurs in the report generation process.

  missing_reason()
Reports why the subreport is missing. This will be undefined when the subreport is not missing.

  superservice()
Returns the superservice of this subreport. This is the superservice that defined the report specification from which the subreport was generated.

  type()
Returns the type of this subreport. This is the ID of the report specification that was used to generate this subreport.

  schemas( [ $schema, ... ] )
Returns the schemas used by this Subreport.

  field_schema( $field )
Returns the schema which contain field $field. Returns undef if this name isn't defined in any schema.

  chart_configs()
Returns an array reference containing Lire::Report::ChartConfig objects specifying the charts that should be generated from this Subreport.

  add_chart_config( $chart_config )
Adds a Lire::Report::ChartConfig object specifying a chart that should be generated from this Subreport's data.

  title( [$title] )
Returns the subreport's title.

If the $title is parameter is set, the subreport's title will be set to this new value.

  description( [$new_desc] )
Returns this subreport's description. The description is encoded in DocBook XML.

If the $description parameter is set, this method will set this subreport's description to this new value. If the $description parameter is undef, that description will be removed.

  table_info( [$table_info] )
Returns the top-level Lire::Report::TableInfo object describing this table layout. If $table_info parameter is set, the subreport table info will be set to this object.

  nrows()
Returns the number of rows in the table.

  last_row_idx()
Returns the index of the last row of data.

  getrow_by_idx( $index )
Returns an array reference containing row 'idx' of the subreport data. A row will contain all the values (categorical and numerical) that would appear on the same row. When an entry is made of categorical variables plus nested groups, the group's summary values will appear on the same row than the categorical variable.

Each value is the hash reference that is returned by Entry::data_by_name() for that column and it is in the row at the column's index.

  getrows()
Returns all rows contained in the subreport. This method is useful for rendering the subreport table.

  finalize()
This method should be called after all entries were added. It assign row-idx and computes column width and statistics.
