NAME

Config::Objective::List - list data type class for Config::Objective

CONTENTS

SYNOPSIS



  use Config::Objective;
  use Config::Objective::List;

  my $conf = Config::Objective->new(filename, {
                        listobj       => Config::Objective::List->new()
                });



DESCRIPTION

The <B>Config::Objective::ListB> module provides a class that represents a list in an object so that it can be used with <B>Config::ObjectiveB>. Its methods can be used to manipulate the encapsulated list from the config file.

The <B>Config::Objective::ListB> class is derived from the <B>Config::Objective::DataTypeB> class, but it defines/overrides the following methods:
add() Adds the supplied value to the end of the object’s list. The value can be a scalar or a reference to a list, in which case the values in the referenced list are added to the object’s list.
unset() Sets the object’s value to an empty list.
set() The same as add(), except that the existing list is emptied by calling the unset() method before adding the new data.
default() Calls the add() method.
add_top() Same as add, but adds to the front of the list instead of the end.
delete() Deletes elements from the list that match its argument. Matching is performed by using the argument as a regular expression. The argument can be a scalar or a reference to a list, in which case each item of the referenced list is used to check the values in the object’s list.
