SPVM::LongList - Dynamic long Array

Usage

  use LongList;
  
  # Create a long list
  my $list = LongList->new;
  my $list = LongList->new([(long)1, 2, 3]);
  
  # Create a long list with array length
  my $list = LongList->new_len(10);
  
  # Get list length
  my $length = $list->length;
  
  # Push value
  $list->push((long)3);
  
  # Pop value.
  my $value = $list->pop;
  
  # Unshift value.
  $list->unshift((long)3);
  
  # Shift value.
  my $value = $list->shift;
  
  # Set value.
  $list->set(2, (long)3);
  
  # Get value.
  my $value = $list->get(2);
  
  # Insert value
  $list->insert(1, 3);
  
  # Remove value
  my $value = $list->remove(1);
  
  # Convert list to array.
  my $array = $list->to_array;
  

Description

LongList is a dynamic long 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.

values

  has values : ro long[];

The values of the list. This is the internally used array, but it can be manipulated directly.

  my $values = $list->values;
  $valeus->[0] = 5;

Class Methods

new

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

Create a new LongList 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 values of the array are copied to the values of the the created array.

Examples:

  my $list = LongList->new;
  my $list = LongList->new([(long)1, 2, 3]);

new_len

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

Create a new LongList object with the length and the capacity.

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

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

The length must be greater than or equal to 0. Otherwise an excpetion will be thrown.

Instance Methods

get

  method get : long ($index : int)

Get the element of the position of the index.

The index must be greater than or equal to 0. Otherwise an excpetion will be thrown.

The index must be less than the length of the list. Otherwise an excpetion will be thrown.

insert

  method insert : void ($index : int, $value : long)

Insert an element to the position of the index.

The index must be greater than or equal to 0. Otherwise an excpetion will be thrown.

The index must be less than or equal to the length of the list. Otherwise an excpetion will be thrown.

pop

  method pop : long ()

Remove the last element and return it.

The length of the list must be greater than 0. Otherwise an excpetion will be thrown.

push

  method push : void ($value : long)

Add an element after the end of the list.

remove

  method remove : long ($index : int)

Remove the element at the position of the index and return it.

The index must be greater than or equal to 0. Otherwise an excpetion will be thrown.

The index must be less than the length of the list. Otherwise an excpetion will be thrown.

replace

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

Replace the elements of the range specified by the offset and the lenght with the replacement array.

The offset must be greater than or equal to 0. Otherwise an excpetion will be thrown.

The removing length must be greater than or equal to 0. Otherwise an excpetion will be thrown.

The offset + the removing lenght must be less than or equal to the length of the list. Otherwise an excpetion will be thrown.

reserve

  method reserve : void ($new_capacity : int)

Reserve the elements with the new capacity.

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

Note that "values" is replaced with the new values and the values of the original list are copied to the new values in the above case.

The new capacity must be greater than or equal to 0. Otherwise an excpetion will be thrown.

resize

  method resize : void ($new_length : int)

Resize the list.

The new length must be greater than or equal to 0. Otherwise an excpetion will be thrown.

set

  method set : void ($index : int, $value : long)

Set the element at the position of the index.

The index must be greater than or equal to 0. Otherwise an excpetion will be thrown.

The index must be less than the length of the list. Otherwise an excpetion will be thrown.

set_array

  method set_array : void ($array : long[])

Set an array. Each element of the array is copied to the element of the list.

The array must be defined. Otherwise an excpetion will be thrown.

The length of the array must be the same as the length of the list. Otherwise an excpetion will be thrown.

shift

  method shift : long ()

Remove the first element and return it.

The length of the list must be greater than 0. Otherwise an excpetion will be thrown.

to_array

  method to_array : long[] ()

Convert the list to an array.

unshift

  method unshift : void ($value : long)

Insert an element at the beginning of the list.
