NAME
Spreadsheet::XLSX::Reader::LibXML::Row - XLSX Row data class
DESCRIPTION
This documentation is written to explain ways to use this module when writing your own excel parser. To use the general package for excel parsing out of the box please review the documentation for Workbooks, Worksheets, and Cells
This module provides the basic storage and manipulation of row data (for worksheet files). It does not provide the final view of a given cell. The final view of the cell is collated with the role (Interface) Spreadsheet::XLSX::Reader::LibXML::Worksheet.
All positions (row and column places and integers) at this level are stored and returned in count from one mode!
Modification of this module probably means a rework of the Worksheet level module Spreadsheet::XLSX::Reader::LibXML::XMLReader::WorksheetToRow. Review the attributes "_old_row_inst" in Spreadsheet::XLSX::Reader::LibXML::XMLReader::WorksheetToRow and "_new_row_inst" in Spreadsheet::XLSX::Reader::LibXML::XMLReader::WorksheetToRow for more details.
Attributes
Data passed to new when creating an instance. For access to the values in these attributes see the listed 'attribute methods'. For general information on attributes see Moose::Manual::Attributes. For ways to manage the instance when opened see the Public Methods.
row_number
Definition: Stores the row number of the row data in count from 1
Default: none
Range: positive integers > 0
attribute methods Methods provided to adjust this attribute
get_row_number
Definition: return the attribute value
row_span
Definition: Stores an array ref of two integers representing the start and end columns in count from 1
Default: none
Range: [ 2 positive integers > 0 ]
attribute methods Methods provided to adjust this attribute
set_row_span
Definition: sets the attribute
has_row_span
Definition: predicate for the attribute
trait ['Array']
delegated methods - (curried)
get_row_start => [ 'get' => 0 ], # Get the first position
get_row_end => [ 'get' => 1 ], # Get the second position
row_last_value_column
Definition: Stores the column with a value in it in count from 1
Default: none
Range: positive integers > 0
attribute methods Methods provided to adjust this attribute
get_last_value_column
Definition: return the attribute value
row_formats
Definition: this is an open ended hashref with format values stored for the row
Default: none
Range: a hash ref
attribute methods Methods provided to adjust this attribute
set_row_formats
Definition: sets the attribute
trait ['Hash']
delegated methods
get_row_format => 'get'
row_value_cells
Definition: Stores an array ref of information about cells with values for that row (in order). The purpose of only storing the values is to allow for 'next_value' calls. The actual position of the cell column is stored in the cell hash and the attribute column_to_cell_translations.
Default: an ArrayRef[HashRef] with at least one column HashRef set
Range: ArrayRef[HashRef]
attribute methods Methods provided to adjust this attribute
get_row_value_cells
Definition: gets the stored attribute value
trait ['Array']
delegated methods
get_cell_position => 'get'
total_cell_positions => 'count'
column_to_cell_translations
Definition: only cells with values are stored but you may want to know if a cell has a value based on a column number or you may want to know where the contents of a cell containing values are base on a column number. This attribute stores that lookup table.
Default: an ArrayRef with at least one column position set
Range: ArrayRef
trait ['Array']
delegated methods
get_position_for_column => 'get'
Methods
These are the methods provided by this class for use within the package but are not intended to be used by the end user. Other private methods not listed here are used in the module but not used by the package. If the private method is listed here then replacement of this module either requires replacing them or rewriting all the associated connecting roles and classes. All methods here are assumed to be in count from 1 mode to since the role instances are meant to be managed in the background for the worksheet.
get_the_column( $column )
Definition: This returns the value stored at the desired column position. It also stores this position as the last column retrieved for any 'next_*' calls
Accepts: $column (integer)
Returns: a hashref of cell values at that column, undef for no values, or 'EOR' for positions past the end of the row.
get_the_next_value_position
Definition: This returns the next set of cell values or 'EOR' for positions past the end of the row. When a set of cell values is returned (not EOR) the new 'last' position is recorded.
Accepts: nothing
Returns: a hashref of key value pairs or 'EOR'
get_row_all
Definition: This is a way to get an array of hashrefs that are positioned correctly in count from zero locations for the row data. Just value cells can be returned with get_row_value_cells. For cells with no value between the value cells undef is stored. For cells past the last value even if they fall inside the row span no positions are created.
Accepts: nothing
Returns: an arrayref of hashrefs
