Detailed Documentation

This class represents the main Data representation node.

Deprecated The Inference Engine API is deprecated and will be removed in the 2024.0 release. For instructions on transitioning to the new API, please refer to https://docs.openvino.ai/latest/openvino_2_0_transition_guide.html

The NN graphs are di-graphs consisting of data nodes and layer nodes.

Construction

Data(, , )

An empty constructor (dimensionless)

Parameters:

name	Name of the data node
_precision	Precision of the data
layout	Data layout

Data(, )

A constructor with tensor descriptor.

Parameters:

name	Name of the data node
desc	Tensor descriptor

Data()

A copy constructor.

Parameters:

data	A data object to copy from

Methods

Data&const Data& operator = ()

An assignment operator.

Parameters:

data	A data object to copy from

Returns:

An assigned object

bool isInitialized() const

Checks if the current node is resolved.

Returns:

true if resolved, false otherwise.

voidconst SizeVector& setDims()

Sets the data dimensions.

After the current node is marked as resolved.

Parameters:

a_dims

Tensor dimensions to set

voidLayout setLayout()

Sets the layout value for this Data instance.

Parameters:

layout

Layout value to set

voidconst SizeVector&Layout reshape(, )

changes dims and layout at same time

Parameters:

dims	new dimensions
layout	new layout

voidconst std::initializer_list<size_t>&Layout reshape(, )

changes dims and layout at same time

Deprecated Use InferenceEngine::Data::reshape(const SizeVector&, Layout)

Parameters:

dims	new dimensions
layout	new layout

Layout getLayout() const

Gets the layout value for this Data instance.

Returns:

Layout

const TensorDesc& getTensorDesc() const

Gets Tensor descriptor reference.

Returns:

reference to TensorDesc

const Precision& getPrecision() const

Gets a precision type of this Data instance.

Returns:

Precision type

voidconst Precision& setPrecision()

Sets a precision type of this Data instance.

Parameters:

precision

Precision of the data

const SizeVector& getDims() const

Returns:

data dimensions

const std::string& getName() const

Returns:

name of the data object

voidconst std::string& setName()

Sets a name the Data object.

Parameters:

newName

Name of the data node

const UserValue& getUserObject() const

Returns:

convenient arbitrary user data holder
