Name

SPVM::Immutable::DoubleList − Immutable double Array

Description

The Immutable::DoubleList class has methods to manipulate an immutable double array.

Usage

use Immutable::DoubleList;
# Create a double list
my $list = Immutable::DoubleList−>new;
my $list = Immutable::DoubleList−>new([(double)1, 2, 3]);
# Create a double list with array length
my $list = Immutable::DoubleList−>new_len(10);
# Get list length
my $length = $list−>length;
# Get value.
my $element = $list−>get(2);
# Convert list to array.
my $array = $list−>to_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::DoubleList ($array : double[] = undef);"

Create a new Immutable::DoubleList object using "new_len".

The passed length to "new_len" is the length of the array. If the array is undef, the length is 0.

The elements of the array are copied to the elements of the the created array.

Examples:

my $list = Immutable::DoubleList−>new;
my $list = Immutable::DoubleList−>new([(double)1, 2, 3]);

new_len

"static method new_len : Immutable::DoubleList ($length : int);"

Creates a new Immutable::DoubleList object with $length and $capacity.

Exceptions:

$length must be greater than or equal to 0. Otherwise an exception is thrown.

Instance Methods

get

"method get : double ($index : int);"

Gets the element of the position of $index.

If $index is a netative value, $index is set to "length" plus $index.

Exceptions:

$index must be greater than or equal to 0. Otherwise an exception is thrown.

$index must be less than the length of $list.

to_array

"method to_array : double[] ();"

Converts the list to an array.
