Name
SPVM::R::NDArray::AnyObject - N-Dimensional Array of object Type.
Description
R::NDArray::AnyObject class in SPVM represents n-dimensional array of object type.
Usage
use R::NDArray::AnyObject;
my $ndarray = R::NDArray::AnyObject->new({data => [(object)1, 2, 3, 4, 5, 6], dim => [3, 2]});Super Class
Field
data
method data : object[] ();
Same as R::NDArray#data method, but the return type is different.
Class Methods
new
static method new : R::NDArray::AnyObject ($options : object[] = undef);
Creates a new R::NDArray::AnyObject given the options $options and returns it.
This method calls R::NDArray#init method given the options $options.
Instance Methods
create_default_data
method create_default_data : object[] ($length : int = 0);
Creates a default data given the length $length and returns it.
The default data is created by the following code.
my $default_data = new object[$length];Exceptions:
The length $length must be more than or equal to 0. Otherwise an exception is thrown.
elem_to_string
method elem_to_string : string ($data : object[], $data_index : int);
Converts an element $data at index $data_index to a string and returns it.
The string is created by the following code.
my $string = (string)undef;
eval { $string = $elem->(Stringable)->to_string; }elem_assign
method elem_assign : void ($dist_data : object[], $dist_data_index : int, $src_data : object[], $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 : object[], $dist_data_index : int, $src_data : object[], $src_data_index : int);
Clones the element $src_data at index $src_data_index to the element $dist_data at index $dist_data_index.
The clone is created by the following code:
$dist_data->[$dist_data_index] = $src_data->[$src_data_index]->(Cloneable)->clone;elem_is_na
method elem_is_na : int ($data : object[], $data_index : int);
Checks if an element represets NA.
If the element $data at index $data_index is not defined, returns 1, otherwise returns 0.
clone
method clone : R::NDArray::AnyObject ($shallow : int = 0);
Same as R::NDArray#clone method, but the return type is different.
slice
method slice : R::NDArray::AnyObject ($indexes_product : R::NDArray::Int[]);
Same as R::NDArray#slice method, but the return type is different.
