Detailed Description

The interface of Transport Layer objects.

Transport Layer objects are used for enumerating and creating devices accessible by a specific transport layer (like the Pylon1394 or the PylonGigE transport layer).

Member Function Documentation

virtual IPylonDevice* Pylon::IDeviceFactory::CreateDevice ( const CDeviceInfo di)
pure virtualinherited

Creates a camera object from a device info object.

This method accepts either a device info object from a device enumeration or a user-provided device info object. User-provided device info objects can be preset with properties required for a device, e.g. the user-provided name or the serial number. The implementation tries to find a matching camera by using device enumeration. When the device class property is set, the search is limited to the required transport layer.

If the device creation fails, a GenApi::GenericException will be thrown.

Parameters
diDevice info object containing all information needed to identify exactly one device.

Implemented in Pylon::CTlFactory.

virtual IPylonDevice* Pylon::IDeviceFactory::CreateDevice ( const CDeviceInfo di,
const StringList_t InjectedXmlStrings 
)
pure virtualinherited

Creates a camera object from a device info object, injecting additional GenICam XML definition strings. Currently only one injected xml string is supported.

Implemented in Pylon::CTlFactory.

virtual IPylonDevice* Pylon::IDeviceFactory::CreateDevice ( const String_t )
pure virtualinherited

This method is deprecated. Use CreateDevice receiving a CDeviceInfo object that contains the full name as property. Example: IPylonDevice* device = TlFactory.CreateDevice( CDeviceInfo().SetFullName( fullname)); Creates a device by its unique name (i.e. fullname as returned by CDeviceInfo::GetFullName ).

Implemented in Pylon::CTlFactory.

virtual CDeviceInfo Pylon::ITransportLayer::CreateDeviceInfo ( )
pure virtual

Creates and returns an 'empty' Device Info object appropriate for the transport layer.

Device Info objects returned by the CreateDeviceInfo() method are used to create devices from device info objects that are not the result of a device enumeration process but are provided by the user. The user is responsible for filling in the fields of the Device Info object that are needed to identify and create a device.

Example: To open a GigE device for which the IP address is known, the user lets the Transport Layer object create a Device Info object, specifies the IP address and passes the device info object to the CreateDevice() method.

virtual IPylonDevice* Pylon::IDeviceFactory::CreateFirstDevice ( const CDeviceInfo di = CDeviceInfo())
pure virtualinherited

If multiple devices match the provided properties, the first device found is created. The order in which the devices are found can vary from call to call.

Implemented in Pylon::CTlFactory.

virtual IPylonDevice* Pylon::IDeviceFactory::CreateFirstDevice ( const CDeviceInfo di,
const StringList_t InjectedXmlStrings 
)
pure virtualinherited

Creates the first found camera device matching the provided properties, injecting additional GenICam XML definition strings. Currently only one injected xml string is supported.

Implemented in Pylon::CTlFactory.

virtual void Pylon::IDeviceFactory::DestroyDevice ( IPylonDevice )
pure virtualinherited

Destroys a device.

Note
: Never try to delete a pointer to a camera device by calling free or delete. Always use the DestroyDevice method.

Implemented in Pylon::CTlFactory.

virtual int Pylon::IDeviceFactory::EnumerateDevices ( DeviceInfoList_t list,
bool  addToList = false 
)
pure virtualinherited

Retrieves a list of available devices.

The list contains Pylon::CDeviceInfo objects used for the device creation.

By default, the list passed in will be cleared before the device discovery is started.

Parameters
listList to be filled with device info objects.
addToListIf true, the found devices will be added to the list instead of deleting the list.
Returns
Number of devices found.

Implemented in Pylon::CTlFactory.

virtual int Pylon::IDeviceFactory::EnumerateDevices ( DeviceInfoList_t list,
const DeviceInfoList_t filter,
bool  addToList = false 
)
pure virtualinherited

Retrieves a list of available devices filtered by given properties, usable for looking for specific devices.

The list contains Pylon::CDeviceInfo objects used for the device creation. By default, the list passed in will be cleared before the device discovery is started. The filter list can contain a list of device info objects containing properties a device must have, e.g. the user-provided name or the serial number. A device is returned, if it matches the properties of any of the device info objects in the filter list. When the device class property is set in the filter device info objects, the search is limited to the required transport layers.

Parameters
listList to be filled with device info objects.
filterA list of device info objects with user-provided properties that a device can match.
addToListIf true, found devices will be added to the list instead of deleting the list.
Returns
Number of devices found.

Implemented in Pylon::CTlFactory.

virtual int Pylon::ITransportLayer::EnumerateInterfaces ( InterfaceInfoList_t list,
bool  addToList = false 
)
pure virtual

Retrieves a list of available interfaces.

Note
This method is currently only supported by the pylon GenTL consumer transport layer prototype.

The concept of interfaces is not supported by all transport layers. Depending on the transport layer, an interface may represent a frame grabber board, a network card, etc.

By default, the list passed in will be cleared.

If the transport layer doesn't support the interface concept, EnumerateInterfaces() always returns 0.

Parameters
listThe list to be filled with interface info objects
addToListIf true, found devices will be added to the list instead of deleting the list
Returns
Number of interfaces provided by the transport layer.
virtual GenApi::INodeMap* Pylon::ITransportLayer::GetNodeMap ( )
pure virtual

Returns the GenApi node map used for accessing parameters provided by the transport layer.

Returns
NULL, if the transport layer doesn't provide parameters, a pointer to the parameter node map otherwise.
virtual bool Pylon::IDeviceFactory::IsDeviceAccessible ( const CDeviceInfo deviceInfo,
AccessModeSet  mode = Control,
EDeviceAccessiblityInfo pAccessibilityInfo = NULL 
)
pure virtualinherited

This method can be used to check if a camera device can be created and opened.

This method accepts either a device info object from a device enumeration or a user-provided device info object. User-provided device info objects can be preset with properties required for a device, e.g. the user-provided name or the serial number. The implementation tries to find a matching camera by using device enumeration. When the device class property is set, the search is limited to the required transport layer.

Parameters
[in]deviceInfoProperties of the camera device.
[in]modeUsed for defining how a device is accessed. The use of the mode information is transport layer-specific. For IIDC 1394 devices the mode information is ignored. For GigE devices the Exclusive and Control flags are used for defining how a device is accessed.
[in]pAccessibilityInfoOptionally provides more information about why a device is not accessible.
Returns
True if device can be opened with provided access mode.
Precondition
The deviceInfo object properties specify exactly one device. This is the case when the device info object has been obtained using device enumeration.
Error Safety:
Throws a C++ exception, if the preconditions are not met.

Implemented in Pylon::CTlFactory.
