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
