Detailed Documentation¶

The default implementation of OpenVINO operation extensions.

Methods¶

virtual const ov::DiscreteTypeInfo& get_type_info() const

Returns the type info of operation.

Returns:

ov::DiscreteTypeInfo

virtual ov::OutputVector create(
    const ov::OutputVector& inputs,
    ov::AttributeVisitor& visitor
    ) const

Method creates an OpenVINO operation.

Parameters:

inputs	vector of input ports
visitor	attribute visitor which allows to read necessaty arguments

Returns:

vector of output ports

virtual std::vector<ov::Extension::Ptr> get_attached_extensions() const

Returns extensions that should be registered together with this extension class object.

Attached extensions may include frontend extensions that OpenVINO op to framework ops or necessary transformations that should be applied to the network which consist of target op.

Returns:
