SPVM::R::OP::StringBuffer - N-Dimensional Array Operations for R::NDArray::StringBuffer
Description
R::OP::StringBuffer class in SPVM has methods for n-dimensional array operations for R::NDArray::StringBuffer.
Usage
use R::OP::StringBuffer as BUFOP;
my $ndarray_scalar = BUFOP->c(StringBuffer->new("a"));
my $ndarray_scalar = BUFOP->c("a");
my $data = [
StringBuffer->new("a"),
StringBuffer->new("b"),
StringBuffer->new("c"),
StringBuffer->new("d"),
StringBuffer->new("e"),
StringBuffer->new("f")
];
my $ndarray_vector = BUFOP->c($data);
my $ndarray_vector = BUFOP->c([(string)"a", "b", "c", "d", "e", "f"]);
my $ndarray = BUFOP->c($data, [3, 2]);
my $ndarray2 = BUFOP->c($ndarray);Class Methods
c
static method c : R::NDArray::StringBuffer ($data : object of StringBuffer|StringBuffer[]|R::NDArray::StringBuffer|string|string[]|R::NDArray::String, $dim : int[] = undef);
Creates a new R::NDArray::StringBuffer object given the data $data and the dimensions $dim.
Implemetation:
If $data is defined and the type of $data is StringBuffer, $data is set to [(StringBuffer)$data].
If $data is defined and the type of $data is R::NDArray::StringBuffer, $dim is set to $data->(R::NDArray::StringBuffer)->dim unless $dim is defined and $data is set to $data->(R::NDArray::StringBuffer)->data.
If $data is defined and the type of $data is string, $data is set to [StringBuffer->new((string)$data)].
If $data is defined and the type of $data is string[], $data is set to the return value of R::OP::String-c((string[])$data)->to_string_buffer_ndarray->data>.
If $data is defined and the type of $data is R::NDArray::String, $dim is set to $data->(R::NDArray::String)->dim unless $dim is defined and $data is set to $data->(R::NDArray::String)->to_string_buffer_ndarray->data.
And this method calls R::NDArray::StringBuffer#new method given $dim and $data.
Exceptions:
The type of the data $data must be StringBuffer, StringBuffer[], R::NDArray::StringBuffer, string, string[], R::NDArray::String if defined. Othrewise, an exception is thrown.
push
static method push : void ($x_ndarray : R::NDArray::StringBuffer, $y_ndarray : R::NDArray::String);
Performs $x_elem->push($y_elem) method on each element(named $x_elem, $y_elem) of the n-dimensional array $x_ndarray and $y_ndarray, and sets each element of the new n-dimensional array to the each operation result, and returns the new n-dimensional array.
If push method throw an exceptions, $x_elem is unchanged.
Exceptions:
The n-dimensional array $x_ndarray must be defined. Otherwise, an exception is thrown.
The n-dimensional array $y_ndarray must be defined. Otherwise, an exception is thrown.
The dimensions of $x_ndarray must be equal to the dimensions of $y_ndarray. Otherwise, an exception is thrown.
eq
static method eq : R::NDArray::Int ($x_ndarray : R::NDArray::StringBuffer, $y_ndarray : R::NDArray::StringBuffer);
Creates a new R::NDArray::Int object of the same dimensions as the n-dimensional array $x_ndarray for a return value, performs the comparison logic $x_ndarray->elem_cmp($x_ndarray->data, $i, $y_ndarray->data, $i) == 0 on the each element(the index is $i) of the n-dimensional array $x_ndarray and $y_ndarray, and sets each element of the new n-dimensional array to the each operation result, and returns the new n-dimensional array.
Exceptions:
The n-dimensional array $x_ndarray must be defined. Otherwise, an exception is thrown.
The n-dimensional array $y_ndarray must be defined. Otherwise, an exception is thrown.
The dimensions of $x_ndarray must be equal to the dimensions of $y_ndarray. Otherwise, an exception is thrown.
ne
static method ne : R::NDArray::Int ($x_ndarray : R::NDArray::StringBuffer, $y_ndarray : R::NDArray::StringBuffer);
Creates a new R::NDArray::Int object of the same dimensions as the n-dimensional array $x_ndarray for a return value, performs the comparison logic $x_ndarray->elem_cmp($x_ndarray->data, $i, $y_ndarray->data, $i) != 0 on the each element(the index is $i) of the n-dimensional array $x_ndarray and $y_ndarray, and sets each element of the new n-dimensional array to the each operation result, and returns the new n-dimensional array.
Exceptions:
The n-dimensional array $x_ndarray must be defined. Otherwise, an exception is thrown.
The n-dimensional array $y_ndarray must be defined. Otherwise, an exception is thrown.
The dimensions of $x_ndarray must be equal to the dimensions of $y_ndarray. Otherwise, an exception is thrown.
gt
static method gt : R::NDArray::Int ($x_ndarray : R::NDArray::StringBuffer, $y_ndarray : R::NDArray::StringBuffer);
Creates a new R::NDArray::Int object of the same dimensions as the n-dimensional array $x_ndarray for a return value, performs the comparison logic $x_ndarray->elem_cmp($x_ndarray->data, $i, $y_ndarray->data, $i) > 0 on the each element(the index is $i) of the n-dimensional array $x_ndarray and $y_ndarray, and sets each element of the new n-dimensional array to the each operation result, and returns the new n-dimensional array.
Exceptions:
The n-dimensional array $x_ndarray must be defined. Otherwise, an exception is thrown.
The n-dimensional array $y_ndarray must be defined. Otherwise, an exception is thrown.
The dimensions of $x_ndarray must be equal to the dimensions of $y_ndarray. Otherwise, an exception is thrown.
ge
static method ge : R::NDArray::Int ($x_ndarray : R::NDArray::StringBuffer, $y_ndarray : R::NDArray::StringBuffer);

Exceptions:
The n-dimensional array $x_ndarray must be defined. Otherwise, an exception is thrown.
The n-dimensional array $y_ndarray must be defined. Otherwise, an exception is thrown.
The dimensions of $x_ndarray must be equal to the dimensions of $y_ndarray. Otherwise, an exception is thrown.
lt

Creates a new R::NDArray::Int object of the same dimensions as the n-dimensional array $x_ndarray for a return value, performs the comparison logic $x_ndarray->elem_cmp($x_ndarray->data, $i, $y_ndarray->data, $i) < 0 on the each element(the index is $i) of the n-dimensional array $x_ndarray and $y_ndarray, and sets each element of the new n-dimensional array to the each operation result, and returns the new n-dimensional array.
Exceptions:
The n-dimensional array $x_ndarray must be defined. Otherwise, an exception is thrown.
The n-dimensional array $y_ndarray must be defined. Otherwise, an exception is thrown.

Exceptions:
The n-dimensional array $x_ndarray must be defined. Otherwise, an exception is thrown.
The n-dimensional array $y_ndarray must be defined. Otherwise, an exception is thrown.

rep_length
static method rep_length : R::NDArray::StringBuffer ($x_ndarray : R::NDArray::StringBuffer, $length : int);
Same as R::OP#rep_length method, but the return type is different.
