NAME

       Config::Model::ListId - Handle list element for configuration model

VERSION

       version 2.117

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

   sort_algorithm
       Returns  a sub used to sort the list elements. See "sort" in perlfunc. Used only for list of leaves. This
       method can be overridden to alter sort order.
