NAME
Config::Objective::Table - table data type class for Config::Objective
SYNOPSIS
use Config::Objective;
use Config::Objective::Table;
my $conf = Config::Objective->new('filename', {
'tableobj' => Config::Objective::Table->new()
});DESCRIPTION
The Config::Objective::Table module provides a class that represents a table value in an object so that it can be used with Config::Objective. Its methods can be used to manipulate the encapsulated table value from the config file.
The table data is represented as a list of lists. Both rows and columns are indexed starting at 0. It is derived from the Config::Objective::List class, but it supports the following additional methods:
- add_before()
-
Inserts a new row into the table before a specified row. The argument must be a reference to a list containing three elements: a number indicating what column to search on, a string which is used as a regular expression match to find a matching row in the table, and a reference to the new list to be inserted before the matching row.
- find()
-
Finds a row with a specified word in a specified column. The column number is the first argument, and the word to match on is the second. It returns a reference to the matching row, or undef if no matches were found.
This function is not very useful for calling from a config file, but it's sometimes useful to call it from perl once the config file has been read.
- replace()
-
Finds a row in the same manner as find(), and then replaces that row's value in a specified column with a new value. The arguments are the column number to search on, the word to search for, the column number to replace, and the text to replace it with.
- modify()
-
Similar to replace(), but appends to the existing value instead of replacing it. A space character is appended before the new value.
