Stride Constructor

Function Usage

Constructs an object of class Stride.

Prototype

In the following, dim_num_ indicates the number of dimensions, and strides_ indicates the specific step information.

• Constructs a stride by default. In the default stride object, dim_num_ is 0.

  1	Stride() : dim_num_(0), strides_{0}

• Constructs a stride using the strides_ value. For example, Stride({18,9,3,1}) indicates that a stride object is created with four dimensions, and the values of each dimension are 18, 9, 3, and 1.

  1	Stride(const std::initializer_list<int64_t> &args) : Stride()

• Serves as a copy constructor. To improve performance, the space where strides_ exceeds the source stride object dim_num_ is not copied. Dirty data may exist.

  1	Stride(const Stride &other)

• Serves as a copy assignment operator. To improve performance, the space where strides_ exceeds the source stride object dim_num_ is not copied. Dirty data may exist.

  1	Stride &operator=(const Stride &other)

Parameters

Returns

Initialized stride object.

Constraints

None

Examples

1

Stride stride({3, 256, 256}); // The first three dimensions of dim_num_=3  strides_ are 3, 256, and 256.
