Config::Model::ListId(3) Handle list element for configuration model

VERSION

version 2.087

SYNOPSIS

See ``SYNOPSIS'' in Config::Model::AnyId

DESCRIPTION

This class provides list elements for a Config::Model::Node.

CONSTRUCTOR

ListId object should not be created directly.

List model declaration

See model declaration section from Config::Model::AnyId.

Methods

get_type

Returns "list".

fetch_size

Returns the number of elements of the list.

load(string, [ check => 'no' ] )

Store a set of values passed as a comma separated list of values. Values can be quoted strings. (i.e ""a,a",b" yields "('a,a', 'b')" list).

"check" can be yes, no or skip

store_set( ... )

Store a set of values (passed as list)

If tinkering with check is required, use the following way : 

 store_set ( \@v , check => 'skip' );

move ( from_index, to_index, [ check => 'no' )

Move an element within the list. "check" can be 'yes' 'no' 'skip'

push( value1, [ value2 ... ] )

push some values at the end of the list.

push_x ( values => [ v1','v2', ...] , ... )

Like push with extended options. Options are:
check
Check value validaty. Either "yes" (default), "no", "skip"
values
Values to push (array_ref)
value
Single value to push
annotation

unshift( value1, [ value2 ... ] )

unshift some values at the end of the list.

insert_at( idx, value1, [ value2 ... ] )

unshift some values at index idx in the list.

insert_before( ( val | qr/stuff/ ) , value1, [ value2 ... ] )

unshift some values before value equal to "val" or before value matching "stuff".

insort( value1, [ value2 ... ] )

Insert "zz" value on "xxx" list so that existing alphanumeric order is preserved. "insort" yields unpexpected results when called on an unsorted list.

store

Equivalent to push_x. This method is provided to help write configuration parser, so the call is the same when dealing with leaf or list values. Prefer "push_x" when practical.
check
"yes", "no" or "skip"
annotation
list ref of annotation to store with the list values

Example: 

 $elt->push_x (
    values => [ 'v1','v2' ] ,
    annotation => [ 'v1 comment', 'v2 comment' ],
    check => 'skip'
 );

sort()

Sort the content of the list. Can only be called on list of leaf.

swap ( ida , idb )

Swap 2 elements within the array

remove ( idx )

Remove an element from the list. Equivalent to "splice @list,$idx,1"

load_data ( data => ( ref | scalar ) [, check => ... ] [ , split_reg => $re ] )

Clear and load list from data contained in the "data" array ref. If a scalar or a hash ref is passed, the list is cleared and the data is stored in the first element of the list. If split_reg is specified, the scalar is split to load the array.

For instance 

   $elt->load_data( data => 'foo,bar', split_reg => qr(,) ) ;

loads " [ 'foo','bar']" in $elt
