SPVM::DoubleList - Dynamic double Array
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 $value = $list->pop; # Unshift value. $list->unshift((double)3); # Shift value. my $value = $list->shift; # Set value. $list->set(2, (double)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;
DoubleList is a dynamic double array.
DoubleList
double
has length : ro int;
The length.
has values : ro double[];
The values. This is the internally used array, but it can be manipulated directly.
my $values = $list->values; $valeus->[0] = 5;
static method new : DoubleList ($array = undef : double[])
Create a new DoubleList object with a double array.
Internally, a new array is created, and each element of the specified array is copied to the new array.
If the array is undef, a new array that length is 0 is created.
undef
0
Examples:
my $list = DoubleList->new; my $list = DoubleList->new([(double)1, 2, 3]);
static method new_len : DoubleList ($length : int)
Create a new DoubleList object with the length.
The length must be greater than or equal to 0. Otherwise an excpetion will be thrown.
method get : double ($index : int)
Get the element of the position of the index.
The index must be greater than or equal to 0. Otherwise an excpetion will be thrown.
The index must be less than the length of the list. Otherwise an excpetion will be thrown.
method insert : void ($index : int, $value : double)
Insert an element to the position of the index.
The index must be less than or equal to the length of the list. Otherwise an excpetion will be thrown.
method pop : double ()
Remove the last element and return it.
The length of the list must be greater than 0. Otherwise an excpetion will be thrown.
method push : void ($value : double)
Add an element after the end of the list.
method remove : double ($index : int)
Remove the element at the position of the index and return it.
method replace : void ($offset : int, $remove_length : int, $replace : double[])
Replace the elements of the range specified by the offset and the lenght with the replacement array.
The offset must be greater than or equal to 0. Otherwise an excpetion will be thrown.
The removing length must be greater than or equal to 0. Otherwise an excpetion will be thrown.
The offset + the removing lenght must be less than or equal to the length of the list. Otherwise an excpetion will be thrown.
method resize : void ($new_length : int)
Resize the list.
The new length must be greater than or equal to 0. Otherwise an excpetion will be thrown.
method set : void ($index : int, $value : double)
Set the element at the position of the index.
method set_array : void ($array : double[])
Set a 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.
method shift : double ()
Remove the first element and return it.
method to_array : double[] ()
Convert the list to an array.
method unshift : void ($value : double)
Insert an element at the beginning of the list.
