Definition of an unsorted multimap mapping object ids to descriptions.

Constructor & Destructor Documentation

◆ Manager()

Ocean::Devices::Manager::Manager ( )

private

Creates a new manager object.

◆ ~Manager()

virtual Ocean::Devices::Manager::~Manager ( )

privatevirtual

Destructs a manager object.

Member Function Documentation

◆ createUniqueObjectId()

Measurement::ObjectId Ocean::Devices::Manager::createUniqueObjectId ( const std::string & description )

private

Creates a unique object id for a new object (e.g., a tracking object like an image, a marker, or a location).

Parameters

description The description of the new object, must be valid

Returns: The unique id which is unique across all devices

◆ device() [1/2]

DeviceRef Ocean::Devices::Manager::device	(	const Device::DeviceType	type,
		const bool	useExclusive = `false`
	)

Returns a specified device.

Parameters

type	The major type of the device to return
useExclusive	True, if the caller would like to use this device exclusively; False, if the device can be shared

Returns: The requested device, if available

◆ device() [2/2]

DeviceRef Ocean::Devices::Manager::device	(	const std::string &	name,
		const bool	useExclusive = `false`
	)

Returns a specific device.

Parameters

name	The name of the device to return, must be valid
useExclusive	True, if the caller would like to use this device exclusively; False, if the device can be shared

Returns: The requested device, if available

◆ devices() [1/2]

Strings Ocean::Devices::Manager::devices ( ) const

Returns a list with the names of all available devices.

Returns: Device names

◆ devices() [2/2]

Strings Ocean::Devices::Manager::devices ( const Device::DeviceType type ) const

Returns a list with the names of all available devices matching a major and minor device type.

Parameters

type	Type of the device to return

Returns: Device names

◆ isRegistered()

bool Ocean::Devices::Manager::isRegistered ( const std::string & library )

Returns whether a specified library is registered at this manager.

Parameters

library Name of the library to check

Returns: True, if so

◆ libraries()

Strings Ocean::Devices::Manager::libraries ( ) const

Returns the names of all registered libraries.

Returns: Registered library names

◆ nameAdhocFactory()

static std::string Ocean::Devices::Manager::nameAdhocFactory ( )

static

Returns the name of the ad-hoc factory.

The ad-hoc factory is for devices which are implemented outside of an own library e.g., during rapid prototyping.

Returns: The name of the ad-hoc factor

◆ objectDescription()

std::string Ocean::Devices::Manager::objectDescription ( const Measurement::ObjectId objectId ) const

Returns the description of an object id.

Parameters

objectId The object id for which the description will be returned

Returns: The description of the object, empty if the object id is unknown

◆ registerAdhocDevice()

bool Ocean::Devices::Manager::registerAdhocDevice	(	const std::string &	deviceName,
		const Device::DeviceType &	deviceType,
		const AdhocInstanceFunction &	deviceInstanceFunction
	)

Registes an ad-hoc device at this manager.

In general, devices should be implemented in an own decicated plugin-based library. However, for prototyping an ad-hoc device cames with the same features as a device implemented in a dedicatd library without the overhead of writing the code for the plugin mechanisms etc.

Parameters

deviceName	Unique name of the device to register
deviceType	Type of the device
deviceInstanceFunction	Function creating an instance of the device

See also: unregisterAdhocDevice().

◆ registerFactory()

bool Ocean::Devices::Manager::registerFactory ( std::unique_ptr< Factory > && factory )

private

Registers a new factory.

Parameters

factory The factory to register

Returns: True, if the factory hasn't been registered before

◆ release()

void Ocean::Devices::Manager::release ( )

Destructs all registered libraries and their corresponding factories.

◆ unregisterAdhocDevice()

bool Ocean::Devices::Manager::unregisterAdhocDevice ( const std::string & deviceName )

Unregisters a previously registered ad-hoc device from this manager.

Beware: Ensure that the device is not used anymore before unregistering it.

Parameters

deviceName The name of the device to unregister, must be valid

Returns: True, if succeeded

See also: registerAdhocDevice().

◆ unregisterFactory()

bool Ocean::Devices::Manager::unregisterFactory ( const std::string & factory )

private

Unregisters a factory.

Parameters

factory Name of the factory to unregister

Returns: True, if succeeded
