use Immutable::StringList;
# Create a string list
my $list = Immutable::StringList->new;
my $list = Immutable::StringList->new(["abc", "def", "ghi"]);
# Create a string list
my $list = Immutable::StringList->new_len(10);
# Get list length
my $length = $list->length;
# Get string value.
my $element = $list->get(2);
# Convert Immutable::StringList to string array.
my $array = $list->to_array;Description
The Immutable::StringList class has methods to manipulate an immutable string array.
Fields
length
has length : ro int;Gets the length field.
This field is the length of the elements of the list.
Class Methods
new
static method new : Immutable::StringList ($array : string[] = undef);
