SPVM::IntList - Dynamic int Array

Usage

use IntList;

# Create a int list
my $list = IntList->new;
my $list = IntList->new([(int)1, 2, 3]);

# Create a int list with array length
my $list = IntList->new_len(10);

# Get list length
my $length = $list->length;

# Push value
$list->push((int)3);

# Pop value.
my $element = $list->pop;

# Unshift value.
$list->unshift((int)3);

# Shift value.
my $element = $list->shift;

# Set value.
$list->set(2, (int)3);

# Get value.
my $element = $list->get(2);

# Insert value
$list->insert(1, 3);

# Remove value
my $element = $list->remove(1);

# Convert list to array.
my $array = $list->to_array;

Description

IntList is a dynamic int array.

Enumerations

enum {
  DEFAULT_CAPACITY = 4,
}

DEFAULT_CAPACITY

The default capacity. The value is 4.

Fields

capacity

has capacity : ro int;

The capacity. This is the length of the internally reserved elements to extend the length of the list.

length

has length : ro int;

The length of the list.

Class Methods

new

static method new : IntList ($array : int[] = undef, $capacity : int = -1);

Create a new IntList 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 = IntList->new;
my $list = IntList->new([(int)1, 2, 3]);

new_len

static method new_len : IntList ($length : int, $capacity : int = -1);

Creates a new IntList object with $length and $capacity.

If $capacity is less than 0, the capacity is set to the value of "DEFAULT_CAPACITY".

If $length is greater than $capacity, $capacity is set to $length.

Exceptions:

$length must be greater than or equal to 0.

Instance Methods

get

method get : int ($index : int);

Gets the element of the position of $index.

Exceptions:

$index must be greater than or equal to 0.

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

insert

method insert : void ($index : int, $element : int);

Inserts an $element to the position of $index.

Exceptions:

$index must be greater than or equal to 0.

$index must be less than or equal to the length of $list.

pop

method pop : int ();

Removes the last element and return it.

Exceptions:

The length of $list must be greater than 0.

push

method push : void ($element : int);

Adds an $element after the end of the list.

remove

method remove : int ($index : int);

Removes the element at the position of $index and return it.

Exceptions:

$index must be greater than or equal to 0.

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

replace

method replace : void ($offset : int, $remove_length : int, $replace : int[]);

Replaces the elements of the range specified by $offset and $lenght with $replace array.

Exceptions:

$offset must be greater than or equal to 0.

$remove_length must be greater than or equal to 0.

$offset + $removing lenght must be less than or equal to the length of $list.

reserve

method reserve : void ($new_capacity : int);

Reserves the elements with $new_capacity.

If $new_capacity is greater than the capacity of the list, the capacity of the list is extended to $new_capacity.

Exceptions:

$new_capacity must be greater than or equal to 0.

resize

method resize : void ($new_length : int);

Resize the list with $new_length.

Exceptions:

$new_length must be greater than or equal to 0.

set

method set : void ($index : int, $element : int);

Sets $element at the position of $index.

Exceptions:

$index must be greater than or equal to 0.

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

set_array

method set_array : void ($array : int[]);

Sets an $array. Each element of $array is copied to the element of the list.

Exceptions:

$array must be defined.

The length of $array must be equal to the length of $list.

shift

method shift : int ();

Removes the first element and return it.

Exceptions:

The length of $list must be greater than 0.

to_array

method to_array : int[] ();

Creates a new array with the length of the list and copies all elements of the list into the new array, and returns it.

get_array_unsafe

method get_array_unsafe : int[] ();

Gets the internally array.

This array is unsafe because it continues to point to the old array if the internal array is extended.

unshift

method unshift : void ($element : int);

Inserts an $element at the beginning of the list.
