Name

SPVM::R::NDArray::Time::Piece - N-Dimensional Array of Time::Piece Type.

Description

R::NDArray::Time::Piece class in SPVM represents n-dimensional array of Time::Piece type.

Usage

  use R::NDArray::Time::Piece;
  
  my $data = [
    Time::Piece->strptime("2024-01-01 00-00-00", '%Y-%m-%d %H:%M:%S'),
    Time::Piece->strptime("2024-01-02 00-00-00", '%Y-%m-%d %H:%M:%S'),
    Time::Piece->strptime("2024-01-03 00-00-00", '%Y-%m-%d %H:%M:%S'),
    Time::Piece->strptime("2024-01-04 00-00-00", '%Y-%m-%d %H:%M:%S'),
    Time::Piece->strptime("2024-01-05 00-00-00", '%Y-%m-%d %H:%M:%S'),
    Time::Piece->strptime("2024-01-06 00-00-00", '%Y-%m-%d %H:%M:%S'),
  ];
  
  my $ndarray = R::NDArray::Time::Piece->new({data => $data, dim => [3, 2]});

Super Class

R::NDArray

Field

data

method data : Time::Piece[] ();

Same as R::NDArray#data method, but the return type is different.

Class Methods

static method new : R::NDArray::Time::Piece ($options : object[] = undef);

Creates a new R::NDArray::Time::Piece and returns it.

This method calls R::NDArray#init method given the options $options.

Instance Methods

create_default_data

method create_default_data : Time::Piece[] ($length : int = 0);

Creates a default data given the length $length and returns it.

elem_to_string

method elem_to_string : string ($data : Time::Piece[], $data_index : int);

Converts an element $data at index $data_index to a string and returns it.

elem_assign

method elem_assign : void ($dist_data : Time::Piece[], $dist_data_index : int, $src_data : Time::Piece[], $src_data_index : int);

Assigns the element $src_data at index $src_data_index to the element $dist_data at index $dist_data_index.

elem_clone

method elem_clone : void ($dist_data : Time::Piece[], $dist_data_index : int, $src_data : Time::Piece[], $src_data_index : int);

Copies the element $src_data at index $src_data_indext to the element $dist_data at index $dist_data_index.

elem_cmp

method elem_cmp : int ($data : Time::Piece[], $a_data_index : int, $b_data_index : int);

Compares the element $data at index $a_data_index and the element $data at index $b_data_index and returns the result.

clone

method clone : R::NDArray::Time::Piece ($shallow : int = 0);

Same as R::NDArray#clone method, but the return type is different.

slice

method slice : R::NDArray::Time::Piece ($asix_indexes_product : R::NDArray::Int[]);

Same as R::NDArray#slice method, but the return type is different.

to_long_ndarray

method to_long_ndarray : R::NDArray::Long ();

Converts this n-dimensional array to a n-dimensional array of R::NDArray::Long using Time::Piece#epoch method and returns it.
