Detailed Documentation¶

IReader an abstract interface for Inference Engine readers.

Methods¶

virtual bool supportModel(std::istream& model) const = 0

Checks that reader supports format of the model.

Parameters:

model

stream with model

Returns:

true if format is supported

virtual CNNNetwork read(
    std::istream& model,
    const std::vector<IExtensionPtr>& exts
    ) const = 0

Reads the model to CNNNetwork.

Parameters:

model	stream with model
exts	vector with extensions

Returns:

CNNNetwork

virtual CNNNetwork read(
    std::istream& model,
    const Blob::CPtr& weights,
    const std::vector<IExtensionPtr>& exts
    ) const = 0

Reads the model to CNNNetwork.

Parameters:

model	stream with model
weights	stream with binary data
exts	vector with extensions

Returns:

CNNNetwork

virtual std::vector<std::string> getDataFileExtensions() const = 0

Returns all supported extensions for data files.

Returns:

vector of file extensions, for example the reader for OpenVINO IR returns {“bin”}
