Detailed Documentation

An API of plugin to be implemented by a plugin.

Typedefs

typedef std::shared_ptr<IInferencePlugin> Ptr

A shared pointer to IInferencePlugin interface.

Methods

void SetVersion(const Version& version)

Sets a plugin version.

Parameters:

version

A version to set

const Version& GetVersion() const

Gets a plugin version.

Returns:

A const InferenceEngine::Version object

virtual std::string GetName() const

Provides a name of a plugin.

Returns:

The name.

virtual void SetName(const std::string& name)

Sets a name for a plugin.

Parameters:

name

The name

virtual std::shared_ptr<IExecutableNetworkInternal> LoadNetwork(
    const CNNNetwork& network,
    const std::map<std::string, std::string>& config
    )

Creates an executable network from an pares network object, users can create as many networks as they need and use them simultaneously (up to the limitation of the HW resources)

Parameters:

network	A network object acquired from InferenceEngine::Core::ReadNetwork
config	A string-string map of config parameters relevant only for this load operation

Returns:

Created Executable Network object

virtual std::shared_ptr<IExecutableNetworkInternal> LoadNetwork(
    const CNNNetwork& network,
    const std::map<std::string, std::string>& config,
    const std::shared_ptr<RemoteContext>& context
    )

Creates an executable network from network object, on specified remote context.

Parameters:

network	A network object acquired from InferenceEngine::Core::ReadNetwork
config	string-string map of config parameters relevant only for this load operation
context	A pointer to plugin context derived from RemoteContext class used to execute the network

Returns:

Created Executable Network object

virtual std::shared_ptr<IExecutableNetworkInternal> LoadNetwork(
    const std::string& modelPath,
    const std::map<std::string, std::string>& config
    )

Creates an executable network from model file path.

Parameters:

modelPath	A path to model
config	A string-string map of config parameters relevant only for this load operation

Returns:

Created Executable Network object

virtual void AddExtension(const std::shared_ptr<IExtension>& extension)

Registers extension within plugin.

Parameters:

extension

pointer to already loaded extension

virtual void SetConfig(const std::map<std::string, std::string>& config)

Sets configuration for plugin, acceptable keys can be found in ie_plugin_config.hpp.

Parameters:

config

string-string map of config parameters

virtual Parameter GetConfig(
    const std::string& name,
    const std::map<std::string, Parameter>& options
    ) const

Gets configuration dedicated to plugin behaviour.

Parameters:

name	value of config corresponding to config key
options	configuration details for config

Returns:

Value of config corresponding to config key

virtual Parameter GetMetric(
    const std::string& name,
    const std::map<std::string, Parameter>& options
    ) const

Gets general runtime metric for dedicated hardware.

Parameters:

name	metric name to request
options	configuration details for metric

Returns:

Metric value corresponding to metric key

virtual std::shared_ptr<RemoteContext> CreateContext(const ParamMap& params)

Creates a remote context instance based on a map of parameters.

Parameters:

params

The map of parameters

Returns:

A remote context object

virtual std::shared_ptr<RemoteContext> GetDefaultContext(const ParamMap& params)

Provides a default remote context instance if supported by a plugin.

Parameters:

params

The map of parameters

Returns:

The default context.

virtual std::shared_ptr<IExecutableNetworkInternal> ImportNetwork(
    const std::string& modelFileName,
    const std::map<std::string, std::string>& config
    )

Creates an executable network from an previously exported network.

Deprecated Use ImportNetwork(std::istream& networkModel, const std::map<std::string, std::string>& config)

Parameters:

modelFileName	path to the location of the exported file
config	A string -> string map of parameters

Returns:

An Executable network

virtual std::shared_ptr<IExecutableNetworkInternal> ImportNetwork(
    std::istream& networkModel,
    const std::map<std::string, std::string>& config
    )

Creates an executable network from an previously exported network using plugin implementation and removes Inference Engine magic and plugin name.

Parameters:

networkModel	Reference to network model output stream
config	A string -> string map of parameters

Returns:

An Executable network

virtual std::shared_ptr<IExecutableNetworkInternal> ImportNetwork(
    std::istream& networkModel,
    const std::shared_ptr<RemoteContext>& context,
    const std::map<std::string, std::string>& config
    )

Creates an executable network from an previously exported network using plugin implementation and removes Inference Engine magic and plugin name.

Parameters:

networkModel	Reference to network model output stream
context	A pointer to plugin context derived from RemoteContext class used to execute the network
config	A string -> string map of parameters

Returns:

An Executable network

virtual void SetCore(std::weak_ptr<ov::ICore> core)

Sets pointer to ICore interface.

Parameters:

core	Pointer to Core interface

virtual std::shared_ptr<ov::ICore> GetCore() const

Gets reference to ICore interface.

Returns:

Reference to ICore interface

const std::shared_ptr<ExecutorManager>& executorManager() const

Gets reference to tasks execution manager.

Returns:

Reference to ExecutorManager interface

virtual QueryNetworkResult QueryNetwork(
    const CNNNetwork& network,
    const std::map<std::string, std::string>& config
    ) const

Queries a plugin about supported layers in network.

Parameters:
