DESCRIPTION

SPVM::DoubleList is continuous dynamic double array.

CLASS METHODS

new

    sub new : SPVM::DoubleList ()

Create a new SPVM::DoubleList object.

newa

    sub newa : SPVM::DoubleList ($array : double[])

Create a new SPVM::DoubleList object with specific double array.

INSTANCE METHODS

length

  sub length : int ()

Get list length.

push

  sub push : void ($self : self, $value : double)

Appending the value to the end of list.

pop

  sub pop : double ($self : self)

Pops and returns the last value of the list, shortening the array by one element If there are no elements in the list, exception occur.

unshift

  sub unshift : void ($self : self, $value : double)

Appending the value to the top of list.

shift

  sub shift : double ($self : self)

Shifts the first value of the list off and returns it, shortening the array by 1 and moving everything down. If there are no elements in the list, exception occur.

set

  sub set : void ($self : self, $index : int, $value : double)

Set the value with index.

get

  sub get : double ($self : self, $index : int)

Get the value with index.

insert

  sub insert : void ($self : self, $index : int, $value : double)

Insert a element to the specific index.

remove

  sub remove : double ($self : self, $index : int)

Remove and return the element which is specified by the index.

to_array

  sub to_array : double[] ($self : self)

Convert SPVM::DoubleList to double array.
