SPVM::DoubleList - Dynamic double Array
Usage
use DoubleList;
# Create a double list
my $list = DoubleList->new;
my $list = DoubleList->new([(double)1, 2, 3]);
# Create a double list with array length
my $list = DoubleList->new_len(10);
# Get list length
my $length = $list->length;
# Push value
$list->push((double)3);
# Pop value.
my $element = $list->pop;
# Unshift value.
$list->unshift((double)3);
# Shift value.
my $element = $list->shift;
# Set value.
$list->set(2, (double)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 = $list->to_array;Description
DoubleList is a dynamic double array.
Fields
capacity
has capacity : ro int;The capacity. This is the length of the internally reserved elements to extend the length of the list.
length
has length : ro int;The length of the list.
Class Methods
new
static method new : DoubleList ($array : double[] = undef, $capacity : int = -1);
Create a new 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 = DoubleList->new;
my $list = DoubleList->new([(double)1, 2, 3]);new_len
static method new_len : DoubleList ($length : int, $capacity : int = -1);
Creates a new DoubleList object with $length and $capacity.
If $capacity is less than 0, the capacity is set to the default value.
If $length is greater than $capacity, $capacity is set to $length.
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.
Exceptions:
$index must be greater than or equal to 0. Otherwise an exception is thrown.
$index must be less than the length of $list.
insert
method insert : void ($index : int, $element : double);
Inserts an $element to the position of $index.
Exceptions:
$index must be greater than or equal to 0. Otherwise an exception is thrown.
$index must be less than or equal to the length of $list.
pop
method pop : double ();
Removes the last element and return it.
Exceptions:
The length of $list must be greater than 0. Otherwise an exception is thrown.
push
method push : void ($element : double);
Adds an $element after the end of the list.
remove
method remove : double ($index : int);
Removes the element at the position of $index and return it.
Exceptions:
$index must be greater than or equal to 0. Otherwise an exception is thrown.
$index must be less than the length of $list. Otherwise an exception is thrown.
replace
method replace : void ($offset : int, $remove_length : int, $replace : double[]);
Replaces the elements of the range specified by $offset and $lenght with $replace array.
Exceptions:
$offset must be greater than or equal to 0. Otherwise an exception is thrown.
$remove_length must be greater than or equal to 0. Otherwise an exception is thrown.
$offset + $removing lenght must be less than or equal to the length of $list. Otherwise an exception is thrown.
reserve
method reserve : void ($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:
$new_capacity must be greater than or equal to 0. Otherwise an exception is thrown.
resize
method resize : void ($new_length : int);
Resize the list with $new_length.
Exceptions:
$new_length must be greater than or equal to 0. Otherwise an exception is thrown.
set
method set : void ($index : int, $element : double);
Sets $element at the position of $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. Otherwise an exception is thrown.
shift
method shift : double ();
Removes the first element and return it.
Exceptions:
The length of $list must be greater than 0. Otherwise an exception is thrown.
to_array
method to_array : double[] ();
Creates a new array with the length of the list and copies all elements of the list into the new array, and returns it.
get_array_unsafe
method get_array_unsafe : double[] ();
Gets the internally array.
This array is unsafe because it continues to point to the old array if the internal array is extended.
unshift
method unshift : void ($element : double);
Inserts an $element at the beginning of the list.
