Struct TensorObject

struct TensorObject

Handle for interacting with Morpheus Tensor objects. Typically constructed using the Tensor::create factory method.

Public Functions

template<typename T, RankType N>
inline T read_element(const std::array<TensorIndex, N> idx) const
inline TensorObject &swap(TensorObject &&other) noexcept

Explicitly swap the pointers to the underlying data with another tensor. Use inplace of the move operator since it’s hard to determine when you want to perform a move vs copy the data.

Returns

TensorObject&

inline TensorObject &operator=(const TensorObject &other)
inline std::shared_ptr<ITensor> get_tensor() const
inline std::shared_ptr<MemoryDescriptor> get_memory() const
inline std::string get_numpy_typestr() const
inline TensorObject as_type(DType dtype) const
inline TensorObject copy_rows(const std::vector<RangeType> &selected_rows, TensorIndex num_rows) const

Creates a deep copy of the rows specified in the exclusive ranges of vector<pair<start, stop>> of the stop row.

Parameters
  • selected_rows

  • num_rows

Returns

TensorObject

Protected Functions

void throw_on_invalid_storage()

Friends

inline friend void swap(TensorObject &lhs, TensorObject &rhs) noexcept

Swap this tensor with another. Only the pointers to the enderlying data are exchanged. No values are moved.
