Constructor & Destructor Documentation

§ Extension()

InferenceEngine::Extension::Extension ( const file_name_t & name )

inlineexplicit

Loads extension from a shared library.

Parameters

name	Full or relative path to extension library

Member Function Documentation

§ getFactoryFor()

StatusCode InferenceEngine::Extension::getFactoryFor	(	ILayerImplFactory *&	factory,
		const CNNLayer *	cnnLayer,
		ResponseDesc *	resp
	)

inlineoverridevirtualnoexcept

Gets the factory with implementations for a given layer.

Deprecated:: Use IExtension::getImplementation to get a concrete implementation. The method will be removed in 2021.1 release.

Parameters

factory	Factory with implementations
cnnLayer	A layer to get the factory for
resp	Response descriptor

Returns: Status code

Reimplemented from InferenceEngine::IExtension.

§ getImplementation()

ILayerImpl::Ptr InferenceEngine::Extension::getImplementation	(	const std::shared_ptr< ngraph::Node > &	node,
		const std::string &	implType
	)

inlineoverridevirtual

Returns implementation for specific nGraph op.

Parameters

node	shared pointer to nGraph op
implType	implementation type

Returns: shared pointer to implementation

Reimplemented from InferenceEngine::IExtension.

§ getImplTypes()

std::vector<std::string> InferenceEngine::Extension::getImplTypes ( const std::shared_ptr< ngraph::Node > & node )

inlineoverridevirtual

Returns vector of implementation types.

Parameters

node	shared pointer to nGraph op

Returns: vector of strings

Reimplemented from InferenceEngine::IExtension.

§ getOpSets()

std::map<std::string, ngraph::OpSet> InferenceEngine::Extension::getOpSets ( )

overridevirtual

Returns operation sets This method throws an exception if it was not implemented.

Returns: map of opset name to opset

Reimplemented from InferenceEngine::IExtension.

§ getPrimitiveTypes()

StatusCode InferenceEngine::Extension::getPrimitiveTypes	(	char **&	types,
		unsigned int &	size,
		ResponseDesc *	resp
	)

inlineoverridevirtualnoexcept

Gets the array with types of layers which are included in the extension.

Deprecated:: Use IExtension::getImplTypes to get implementation types for a particular node. The method will removed in 2021.1 release.

Parameters

types	Types array
size	Size of the types array
resp	Response descriptor

Returns: Status code

Reimplemented from InferenceEngine::IExtension.

§ getShapeInferImpl()

		const char *	type,
		ResponseDesc *	resp
	)

inlineoverridevirtualnoexcept

Gets shape propagation implementation for the given string-type of CNNLayer.

Deprecated:: Implement ngraph::op::Op::validate_and_infer_types method in a custom ngraph operation The method will be removed in 2021.1 release.

Parameters

impl	the vector with implementations which is ordered by priority
type	A type of CNNLayer
resp	response descriptor

Returns: status code

Implements InferenceEngine::IShapeInferExtension.

§ getShapeInferTypes()

StatusCode InferenceEngine::Extension::getShapeInferTypes	(	char **&	types,
		unsigned int &	size,
		ResponseDesc *	resp
	)

inlineoverridevirtualnoexcept

Gets the array with types of layers which are included in the extension.

Deprecated:: Implement ngraph::op::Op::validate_and_infer_types method in a custom ngraph operation The method will be removed in 2021.1 release.

Parameters

types	Types array
size	Size of the types array
resp	Response descriptor

Returns: Status code

§ GetVersion()

void InferenceEngine::Extension::GetVersion ( const InferenceEngine::Version *& versionInfo ) const

inlineoverridevirtualnoexcept

Parameters

versionInfo A pointer to version info, set by the plugin

Implements InferenceEngine::IShapeInferExtension.

§ SetLogCallback()

void InferenceEngine::Extension::SetLogCallback ( InferenceEngine::IErrorListener & listener )

inlineoverridevirtualnoexcept

Sets a log callback that is used to track what is going on inside.

Deprecated:: IErrorListener is not used anymore. StatusCode is provided in case of unexpected situations The method will be removed in 2021.1 release.

Parameters

listener Logging listener
