Construction¶

Extension(const std::string& name)

Loads extension from a shared library.

Parameters:

name	Full or relative path to extension library

Extension(const std::wstring& name)

Loads extension from a shared library.

Parameters:

name	Full or relative path to extension library

Methods¶

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

Gets the extension version information.

Parameters:

versionInfo

A pointer to version info, set by the plugin

virtual void Unload()

Cleans the resources up.

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
