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 $element = $list->pop;
# Unshift value.
$list->unshift((long)3);
# Shift value.
my $element = $list->shift;
# Set value.
$list->set(2, (long)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
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 elements of the list. This is the internally used array, but it can be manipulated directly.
my $elements = $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 elements 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);Creates 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.
Exceptions:
The $length must be greater than or equal to 0.
Instance Methods
get
method get : long ($index : int);Gets the element of the position of the $index.
Exceptions:
The $index must be greater than or equal to 0.
The $index must be less than the length of the $list.
insert
method insert : void ($index : int, $element : long);Inserts an $element to the position of the $index.
Exceptions:
The $index must be greater than or equal to 0.
The $index must be less than or equal to the length of the $list.
pop
method pop : long ();Removes the last element and return it.
Exceptions:
The length of the $list must be greater than 0.
push
method push : void ($element : long);Adds an $element after the end of the list.
remove
method remove : long ($index : int);Removes the element at the position of the $index and return it.
Exceptions:
The $index must be greater than or equal to 0.
The $index must be less than the length of the $list.
replace
method replace : void ($offset : int, $remove_length : int, $replace : long[]);Replaces the elements of the range specified by the $offset and the $lenght with the $replace array.
Exceptions:
The $offset must be greater than or equal to 0.
The $remove_length must be greater than or equal to 0.
The $offset + the $removing lenght must be less than or equal to the length of the $list.
reserve
method reserve : void ($new_capacity : int);Reserves 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.
Exceptions:
The $new_capacity must be greater than or equal to 0.
resize
method resize : void ($new_length : int);Resize the list with the $new_length.
Exceptions:
The $new_length must be greater than or equal to 0.
set
method set : void ($index : int, $element : long);Sets the $element at the position of the $index.
Exceptions:
The $index must be greater than or equal to 0.
The $index must be less than the length of the $list.
set_array
method set_array : void ($array : long[]);Sets an $array. Each element of the $array is copied to the element of the list.
Exceptions:
The $array must be defined.
The length of the $array must be the $same as the length of the $list.
shift
method shift : long ();Removes the first element and return it.
Exceptions:
The length of the $list must be greater than 0.
to_array
method to_array : long[] ();Converts the list to an array.
unshift
method unshift : void ($element : long);Inserts an $element at the beginning of the list.
