Detailed Description

Generic CVB physical device.

A device may provide an image stream or just expose a configuration interface.

See DeviceFactory for creating instances of this object.

Examples: Cvb/QtStreamDisplayPair.

Member Function Documentation

◆ DeviceControl()

Driver::DeviceControlPtr DeviceControl ( ) const

inline

Gets the DeviceControl interface if present.

Returns: Pointer object for accessing the interface; empty pointer if not available.

Exceptions

Any	exception derived from std::exception including CvbException.

◆ DeviceImage() [1/2]

std::shared_ptr< T > DeviceImage ( ) const

inline

Gets, if available, the device image pointing to the last synchronized image.

Returns: Pointer to the device image (casted to the provided type).

Exceptions

Any	exception derived from std::exception including CvbException.

Examples: Cvb/QtStreamDisplayPair.

◆ DeviceImage() [2/2]

DeviceImagePtr DeviceImage ( ) const

inline

Gets, if available, the device image pointing to the latest synchronized image.

Returns: Pointer to the device image.

Exceptions

Any	exception derived from std::exception including CvbException.

◆ DigitalIO()

Driver::DigitalIOPtr DigitalIO ( ) const

inline

Gets the DigitalIO interface if present.

Returns: Pointer object for accessing the interface; empty pointer if not available.

Exceptions

Any	exception derived from std::exception including CvbException.

◆ Handle()

void * Handle ( ) const

inlinenoexcept

Classic API device handle.

Returns: Classic API handle.

Exceptions

Does	not throw any exception.

It is normally not necessary to work with this handle.

◆ ImageRect()

Driver::ImageRectPtr ImageRect ( ) const

inline

Gets the ImageRect interface if present.

Returns: Pointer object for accessing the interface; empty pointer if not available.

Exceptions

Any	exception derived from std::exception including CvbException.

◆ NodeMap()

NodeMapPtr NodeMap ( const String & name ) const

inline

Gets the NodeMap with the given name.

Parameters

[in] name The NodeMap name (String or Cvb::NodeMapID).

Returns: A pointer to the NodeMap

Exceptions

Any	exception derived from std::exception including CvbException.

Example:: auto devices = Cvb::DeviceFactory::Discover(Cvb::DiscoverFlags::IgnoreVins);

auto device = Cvb::DeviceFactory::Open<Cvb::GenICamDevice>(devices.at(0).AccessToken(), Cvb::AcquisitionStack::GenTL);

auto deviceNodeMap = device->NodeMap(Cvb::NodeMapID::Device);

Cvb::DeviceFactory::Discover
static std::vector< DiscoveryInformation > Discover()
Discovers available devices (not vins) with a default time span of 300ms.
Definition: decl_device_factory.hpp:221

◆ NodeMaps()

std::map< String, NodeMapPtr > NodeMaps ( ) const

inline

Gets the dictionary holding all available NodeMaps.

Returns: Dictionary containing all available node maps. Empty if no node map interface is available on this device.

Exceptions

Any	exception derived from std::exception including CvbException.

◆ NotifyObservable()

Driver::NotifyObservablePtr NotifyObservable ( int id ) const

inline

Get the observable for a given id.

Parameters

[in] id The observable id, which is device specific.

Returns: Pointer to the observabel object; empty pointer if not available.

Exceptions

Any	exception derived from std::exception including CvbException.

◆ RegisterConnectionStateChangedEvent()

EventCookie RegisterConnectionStateChangedEvent ( std::function< void()> handler )

inline

Register a listener to the OnDisconnect event.

Parameters

[in] handler Listener, to the OnDisconnect event.

Returns: Event cookie, to manually unregister the listener.

Exceptions

Any	exception derived from std::exception including CvbException.

◆ ResourceLocator()

String ResourceLocator ( ) const

inlinenoexcept

Gets the access token or path of the file name including its extension.

Returns: String containing the access token or rooted path for a file name.

Exceptions

Does	not throw any exception.

◆ SoftwareTrigger()

Driver::SoftwareTriggerPtr SoftwareTrigger ( ) const

inline

Gets the SoftwareTrigger interface if present.

Returns: Pointer object for accessing the interface; empty pointer if not available.

Exceptions

Any	exception derived from std::exception including CvbException.

◆ Stream()

CVB_BEGIN_INLINE_NS Driver::StreamPtr Stream ( ) const

inlinevirtual

Get the stream for this device.

Note: This method is not supported by GenICamDevice.

Deprecated:: This method is deprecated for all technologies providing a GenTL. Use the template version with ImageStream, PointCloudStream or CompositeStream instead.

Returns: Pointer to the stream object.

Exceptions

Any	exception derived from std::exception including CvbException.

Reimplemented in GenICamDevice, and GenICamDevice.

Examples: Cvb/QtStreamDisplayPair.

◆ StreamCount()

int StreamCount ( ) const

inlinenoexcept

Get the number of streams.

Note: Only a GenICamDevice can have more than one stream A NonStreamingDevice does not have a stream!

Returns: Number of streams.

Exceptions

Does	not throw any exception.

◆ UnregisterConnectionStateChangedEvent()

void UnregisterConnectionStateChangedEvent ( EventCookie eventCookie )

inlinenoexcept

Manually unregister a listener to the OnDisconnect event.

Parameters

[in] eventCookie Event cookie, obtained from registering the listener.

Exceptions

Does	not throw any exception.
