| static Value | CreateTensor (OrtAllocator *allocator, const int64_t *shape, size_t shape_len) |
| | Creates an OrtValue with a tensor using a supplied OrtAllocator. Wraps OrtApi::CreateTensorAsOrtValue. This overload will allocate the buffer for the tensor according to the supplied shape and data type. The allocated buffer will be owned by the returned OrtValue and will be freed when the OrtValue is released. The input data would need to be copied into the allocated buffer. This API is not suitable for strings.

The allocated buffer will be owned by the returned OrtValue and will be freed when the OrtValue is released. The input data would need to be copied into the allocated buffer. This API is not suitable for strings.

| static Value | CreateMap (const Value &keys, const Value &values) |

|
| |
| static Value | CreateSequence (const std::vector< Value > &values) |

|
| |
| static Value | CreateSparseTensor (const OrtMemoryInfo *info, void *p_data, const Shape &dense_shape, const Shape &values_shape, ONNXTensorElementDataType type) |
| | Creates an OrtValue instance containing SparseTensor. This constructs a sparse tensor that makes use of user allocated buffers. It does not make copies of the user provided data and does not modify it. The lifespan of user provided buffers should eclipse the life span of the resulting OrtValue. This call constructs an instance that only contain a pointer to non-zero values. To fully populate the sparse tensor call Use<Format>Indices() API below to supply a sparse format specific indices. This API is not suitable for string data. Use CreateSparseTensor() with allocator specified so strings can be properly copied into the allocated buffer.

|
| |
| static Value | CreateSparseTensor (OrtAllocator *allocator, const Shape &dense_shape, ONNXTensorElementDataType type) |
| | Creates an instance of OrtValue containing sparse tensor. The created instance has no data. The data must be supplied by on of the FillSparseTensor<Format>() methods that take both non-zero values and indices. The data will be copied into a buffer that would be allocated using the supplied allocator. Use this API to create OrtValues that contain sparse tensors with all supported data types including strings.
