Methods

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

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

Returns:

map of opset name to opset

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

Returns vector of implementation types.

Parameters:

node	shared pointer to nGraph op

Returns:

vector of strings

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

Returns implementation for specific nGraph op.

Parameters:

node	shared pointer to nGraph op
implType	implementation type

Returns:

shared pointer to implementation

virtual void Unload() = 0

Cleans resources up.

virtual void GetVersion(const InferenceEngine::Version \*& versionInfo) const = 0

Gets extension version information and stores in versionInfo.

Parameters:

versionInfo

Pointer to version info, will be set by plugin

virtual void Release()
